Microsoft has made the famous German Dornier DO X seaplane available to flight simulation enthusiasts. Designed in 1929 by Claude Dornier, this seaplane far surpassed anything else on the market at the time, in terms of weight, length and power.

Unfortunately, the Germans couldn’t make a commercial success of it, as the aircraft was really too heavy to cover long distances at high altitude in an economical way. What’s more, bad experiences were piling up during the various stopovers: the left-wing canvas caught fire in Portugal, there was some problems with tropical weather, the tail was torn off during a poorly-planned ditching in Passau. What remains of the empennage after the accident can now be seen in the Dornier Museum in Friedrichshafen.

The Germans built the three DO X models at Altenheim, on the Swiss side of Lake Constance, to get round the restrictions imposed by the Treaty of Versailles.

One crew member was in charge of controlling and monitoring the engines. He obeyed the captain’s instructions.

The layout of the engines caused headaches for the mechanics. Six propellers pulled the aircraft forward, while another six pushed the DO X. The engines driving the rear propellers received less air than those in front of the aircraft. This led to cooling problems, which reduced reliability on long-distance flights.

On its international routes, the DO X made stopovers in several European countries, Africa, South America, Miami, New York and Newfoundland. At the time, Newfoundland was not yet part of Canada. Newfoundlanders issued a stamp to commemorate the plane’s passage through Hollyrod. Naturally, those who kept a copy of the stamp have seen its value rise sharply over the years.

Books : Our Transatlantic Flight.

Our transatlantic flight, by Sir John Alcock and Sir Arthur Whitten Brown
Our transatlantic flight, by Sir John Alcock and Sir Arthur Whitten Brown

Newfoundland

Before 1949, Newfoundland was called Dominion of Newfoundland   and was part of the British Commonwealth . In 1949, it became a Canadian province.

The first non-stop flight eastward across the Atlantic.

The book « Our transatlantic flight » tells the story of the historic flight that was made in 1919, just after the First World War, from Newfoundland to Ireland. There was a 10,000 £ prize offered by Lord Northcliffe   from Great Britain for whoever would succeed on the first non-stop flight eastward across the Atlantic.

A triumph for British aviation

Sir John Alcock and Sir Arthur Whitten Brown , respectively pilot and navigator, wrote the story of their successful flight in this book which was published in 1969. The followings are pilot quotes from the book : « For the first time in the history of aviation the Atlantic had been crossed in direct, non-stop flight in the record time of 15 hours, 57 minutes. » (p.13) « The flight was a triumph for British aviation; the pilot and navigator were both British, the aircraft was a Vickers-Vimy   and the twin engines were made by Rolls-Royce. » (p.13)

As with all great human achievements, a very good flight planning and some luck was needed to make this flight a success. If there was an engine failure during the flight, even if the planning was excellent, there was only one outcome : downward.

In order to make the flight, Alcock and Brown boarded a ship from England bound to Halifax. They then headed to Port aux Basques and finally arrived in St.John’s. There, they joined a small group of British aviators who had arrived a few days before and who were also preparing for the competition. « The evenings were mostly spent in playing cards with the other competitors at the Cochrane Hotel, or in visits to the neighbouring film theatres. St.John’s itself showed us every kindness. » (p.60)

Maritime transport was used to carry the Vickers-Vimy biplane to Newfoundland on May 4th. It was assembled in Newfoundland. « The reporters representing the Daily Mail, the New York Times, and the New York World were often of assistance when extra manpower was required. » (p.61).

While the aircraft was being built, there were more and more visiters coming to the site. Brown says : « Although we remained unworried so long as the crowd contented itself with just watching, we had to guard against petty damage. The testing of the fabric’s firmness with the point of an umbrella was a favourite pastime of the spectators […]. » (p.61)

The Vickers-Vimy is being reassembled at Quidi Vidi in Newfoundland.

It was difficult to find a field that could be improvised into an aerodrome : « Newfoundland is a hospitable place, but its best friends cannot claim that it is ideal for aviation. The whole of the island has no ground that might be made into a first-class aerodrome. The district around St.John’s is  especially difficult. Some of the country is wooded, but for the most part it shows a rolling, switchback surface, across which aeroplanes cannot taxi with any degree of smoothness. The soil is soft and dotted with boulders, as only a light layer covers the rock stratum. Another handicap is the prevalence of thick fogs, which roll westward from the sea. » (p.59)

They flight tested the airplane on June 9th at Quidi Vidi. During the short flight, the crew could see icebergs near the coast. They did a second trial on June 12th and found that the transmitter constantly caused problems. But, at least, the engines seemed to be reliable…

The departure

The two men left Newfoundland on June 14th 1919. In order to fight the cold air in flight, they wore electrically heated clothing. A battery located between two seats provided for the necessary energy.

The short take-off was very difficult due to the wind and the rough surface of the aerodrome. Brown writes : « Several times I held my breath, from fear that our under-carriage would hit a roof or a tree-top. I am convinced that only Alcock’s clever piloting saved us from such an early disaster. » (p.73)

It took them 8 minutes to reach 1000 ft. Barely one hour after departure and once over the ocean, the generator broke and the flight crew was cut off from all means of communication.

As the airplane consumed petrol, the centre of gravity changed and since there was no trim on the machine, the pilot had to exert a permanent backward pressure on the joystick.

Flying in clouds, fog and turbulence.

During the flight with much clouds and fog, Brown, having almost no navigation aid,  had real problems to estimate the aircraft’s position and limit the flying errors. He had to wait for a higher altitude and for the night to come to improve his calculations : « I waited impatiently for the first sight of the moon, the Pole Star and other old friends of every navigator. » (p.84). The fog and clouds were so thick that at times they « cut off from view parts of the Vickers-Vimy. » (p.95)

Without proper instruments to fly in clouds, they were relying on a « revolution-counter » to establish the climbing or the falling rate. That is pretty scary. « A sudden increase in revolutions would indicate that the plane was diving; a sudden loss of revs  would show that she was climbing dangerously steeply. » (p.176)

But that was not enough. They also had to deal with turbulence that rocked the plane while they could not see anything outside. They became desoriented : « The airspeed indicator failed to register, and bad bumps prevented me from holding to our course. From side to side rocked the machine, and it was hard to know in what position we really were. A spin was the inevitable result. From an altitude of 4,000 feet we twirled rapidly downward.[…]. « Apart from the changing levels marked by aneroid, only the fact that our bodies were pressed tightly against the seats indicated that we were falling. How and at what angle we were falling, we knew not. Alcock tried to centralise the controls, but failed because we had lost all sense of what was central. I searched in every direction for an external sign, and saw nothing but opaque nebulousness. » (p.88)

« It was a tense moment for us, and when at last we emerged from the fog we were close down over the water at an extremely dangerous angle. The white-capped waves were rolling along too close to be comfortable, but a quick glimpse of the horizon enabled me to regain control of the machine. » (p.40).

De-icing a gauge installed outside of the cockpit.

Snow and sleet were falling. They didn’t realize how lucky they were to continue flying in such a weather. Nowadays, there are many ways to dislodge ice from a wing while the aircraft is in flight. Here is what Brown says about their situation : « […] The top sides of the plane were covered completely by a crusting of frozen sleet. The sleet imbedded itself in the hinges of the ailerons and jammed them, so that for about an hour the machine had scarcely any lateral control. Fortunately, the Vickers-Vimy possesses plenty of inherent lateral stability; and, as the rudder controls were never clogged by sleet, we were able to hold to the right direction. » (p.95)

After twelve hours of flying, the glass of a gauge outside the cockpit became obscured by clotted snow. Brown had to deal with it, while Alcock was flying. «  The only way to reach it was by climbing out of the cockpit and kneeling on top of the fuselage, while holding a strut for the maintenance of balance. […] The violent rush of air, which tended to push me backward, was another discomfort. […] Until the storm ended, a repetition of this performance, at fairly frequent intervals, continued to be necessary. » (p.94)

In order to save themselves, they executed a descent from 11,000 to 1000 feet and in the warmer air the ailerons started to operate again. As they continued their descent below 1000 feet over the ocean, they were still surrounded by fog. They had to do some serious low altitude flying : « Alcock was feeling his way downward gently and alertly, not knowing whether the cloud extended to the ocean, nor at what moment the machine’s undercarriage might touch the waves. He had loosened his safety belt, and was ready to abandon ship if we hit the water […]. » (p.96)

The arrival.

They saw Ireland at 8.15 am on June 15th and crossed the coast ten minutes later. They did not expect a very challenging landing as the field looked solid enough to support an aircraft. They landed at 8 :40 am at Clifden on top of what happened to be a bog; the aircraft rolled on its nose and suffered serious material damages. The first non-stop transatlantic flight ended in a crash. Both both crewmen were alive and well, although they were dealing with fatigue

Initially, nobody in Ireland believed that the plane arrived from North America. But when they saw mail-bags from Newfoundland, there were « cheers and painful hand-shakes » (p.102).

Their record stood unchallenged for eight years until Lindbergh’s flight in 1927.

The future of transatlantic flight.

Towards the end of the book, the authors risk a prediction on the future of transatlantic flight. But aviation made such a progress in a very short time that, inevitably, their thoughts on the subject was obsolete in a matter of a few years. Here are some examples :

« Nothwithstanding that the first two flights across the Atlantic were made respectively by a flying boat and an aeroplane, it is evident that the future of transatlantic flight belongs to the airship. » (p.121)

« […] The heavy type of aeroplane necessary to carry an economical load for long distances would not be capable of much more than 85 to 90 miles an hour. The difference between this and the present airship speed of 60 miles an hour would be reduced by the fact that an aeroplane must land at intermediate stations for fuel replenishment. » (p.123)

« It is undesirable to fly at great heights owing to the low temperature; but with suitable provision for heating there is no reason why flying at 10,000 feet should not be common. » (p.136)

The Air Age.

There is a short section in the book on the « Air Age ». I chose two small excerpts on Germany and Canada :

On Germany’s excellent Zeppelins : « The new type of Zeppelin – the Bodensee –  is so efficient that no weather conditions, except a strong cross-hangar wind, prevents it from making its daily flight of 390 miles between Friedrichshafen and Staalsen, thirteen miles from Berlin. » (p.140)

On Canada’s use of aeroplanes : « Canada has found a highly successful use for aeroplanes in prospecting the Labrador timber country. A group of machines returned from an exploration with valuable photographs and maps of hundreds of thousands of pound’s worth of forest land. Aerial fire patrols, also, are sent out over forests.» (p.142) and « Already, the Canadian Northwest Mounted Police [today the RCMP] have captured criminals by means of aeroplane patrols. » (p.146)

Conclusion

The Manchester Guardian stated, on June 16th 1919 : « […] As far as can be foreseen, the future of air transport over the Atlantic is not for the aeroplane. It may be used many times for personal feats of daring. But to make the aeroplane safe enough for business use on such sea routes we should have to have all the cyclones of the Atlantic marked on the chart, and their progress marked in from hour to hour. »(p.169)

This cover was in the first airmail flight between Hong Kong and San Francisco. A Martin M-130, the Pan Am China Clipper, carried the mail. The aircraft left Hong Kong on April 28th, 1937 and arrived in San Francisco on May 4th, 1937. Many stopovers were part of the route and are indicated on the cover.

The China Clipper was destroyed in 1945 when its double hull ruptured due to a collision with an obstacle in the waters of Port-of-Spain, Trininad. The aircraft sank and 23 people were killed. There was only 7 survivors.

Anthologies: le diable à 37,0000 pieds

Le diable à 37000 pieds

(Feuilleton magazine pocket anthology)

Le diable à 37,000 pieds
Le diable à 37,000 pieds

There are seven very interesting articles, in the non-fiction category, in this anthology. Published between 2009 and 2013 in publications like The New Yorker, Vanity Fair, Esquire, Men’s Journal or Q2U.S, they allow the reader to catch-up on events that happened around the planet.

Those stories received a lot of attention from the medias since they covered popular topics like a mid-air collision between two jets, a jewel heist by the Pink Panthers, a botched covered operation by Mossad, wild animals freed by their owner near a small American city, the son of a wealthy American who suddenly leaves United States for Lybia to fight against Khadafi. The reader can also learn more about Apollo Robbins, the king of pickpockets and, finally, comes the weird story of a film making that started in 2006 in Ukraine and is still not ready today.

Le diable à 37,000 pieds (The Devil at 37,000 feet)

This story presents all the elements that contributed to create a mid-air collision: a new crew recently trained on an aircraft loaded with a modern technology that makes flight management more complicated than anything else; air traffic controllers letting their expectations impear their judgment; tired and under pressure careless pilots; passengers disturbing the flying crew by visiting the cockpit on multiple occasions.

It is paradoxal to realize that the extreme precision offered by modern flight navigation equipment also increases the possibility that two aircrafts hit each other in flight.

Pink Panthers

A popular name that sends the reader back to the movies where Peter Sellers played a distracted police inspector. But the article is about the real thing: What circumstances favored the creation and international development of the multiple groups of thiefs that came to be known as the Pink Panthers.

The different Pink Panthers groups have robbed more than 152 jewelry stores since 2002 and pocketed around 250 million dollars. The reader learns that most Pink Panthers members come from the Balkan region and that they operate from Italy, France, Belgium, the Netherlands, Denmark and Switzerland.

The author uses the opportunity to explain how the Milosevic’s gangster regime was put in place in Serbia, a State transformed into a criminal business: “In March 2001, soon after the fall of Milosevic, we discovered, in a safe rented by municipal civil servants from a Belgrade bank, more than 660 kilos of a 93% pure heroin, valued at approximately 100 million dollars on the street”.

Montenegro is also associated with significant banditry and the author tells us about a meeting he had in that region with a former Pink Panthers. In order for criminal groups to survive and develop, there is an essential collaboration with politicians and the border services staff.

Opération Dubaï (Dubaï Operation)

In January 2010, a Mossad team lands in Dubaï with the intention of killing Mahmoud al-mabhouh. The agents are part of an ultra-secret section called “Césarée”. Although they reached their goal, the mission was somewhat a failure since it was possible to determine very rapidly who were the killers, which embarrassed Israël.

The article recounts the general progress of the operation in Dubaï and enhances the important mistakes that eventually damaged the Mossad’s reputation for efficiency.

Here are some of those mistakes:

1. Agents are sitting for hours in a hotel lobby, thus attracting the staff’s attention.

2. Two members of the team head towards the hotel washrooms, where they change their appearance by using a wig and sunglasses, all this while their physical transformation is filmed by an hotel camera positioned near the toilet’s door.

3. The man in charge of planning the covert operation has a huge ego and does not tolerate criticism or a difference of opinion.

4. Carelessness is shown when the team members are equipped with Payoneer prepaid calling cards. Those cards are mostly used in United States and the Payoneer’s director, Yuval Tal, is a veteran of the Israel’s Defence Force elite commando. While they were at it, why not give a Mossad colored business card directly?

5. The person in charge of the operation greatly underestimates the capacity and will of Dubaï’s police force to find the culprits behind Mahmoud al-mabhouh’s death.

6. Every phone call made by the team transit through the same system located in Austria.

An increase in the number of operations lead by Mossad certainly contributed to the non-compliance with respect to the security protocol. Meir Dagan eventually had to step down and the relations between the Mossad and other occidental intelligence services were impacted.

La désertion des animaux du zoo (Animals)

This is a very interesting account of an incident that made the news around the world. At the end of 2011, in Zanesville, Ohio, the owner of about fifty wild animals killed himself, not without having precedently opened the cages of all the wild animals he was keeping on his private property.

The story allows us to share a bit of the emotions lived by the inhabitants living close to the private zoo. We witness the quick reaction and organization needed to face the lions, tigers and bears that are now free to go where they want in the fields near Zanesville. It’s a very well written story.

Vacances de printemps arabe (Arab Spring Break)

This is the story of a rich American who abandons his wealthy neighborhood to go fight against Khadafi in Lybia. This type of story, told with a humoristic approach, was possibly quite amusing in 2012. But with the departure of numerous young kids gone to join ISIS during the past few years, the tone used in the article is now kind of awkward.

Le roi des pickpockets (A Pickpocket’s Tale)

The article is about the life of Apollo Robbins, a now internationally famous pickpocket that has appeared on multiple TV programs around the world, among them National Geographic’s “Brain Games”.

Un tournage pris dans l’engrenage (The Movie Set That Ate Itself)

Through the account of a movie director’s eccentric behaviour in Kharkov, Ukraine, the reader is made aware of the exaggerated control that a human can impose on other persons. It also shows the easiness with which people are ready to accept a totalitarian control in their life. All this while the movie itself is about the dictatorship lived in Russia, more precisely in Moscow, during the fifties and sixties.

Real life stories as a flight service specialist (FSS): Inukjuak FSS

When in doubt, action is worth more than inaction.

(Precedent story: enroute toward the first posting: Inukjuak)

The Inukjuak soft sand runway, in 1982, and a balloon tires equipped Twin Otter, property of Austin Airways.
The Inukjuak soft sand runway, in 1982, and a balloon tires equipped Twin Otter, property of Austin Airways.

During my first working days as a flight service specialist (FSS) at the Transport Canada flight service station in Inukjuak (CYPH), in 1982, I received a radio call from a Twin Beech 200. The pilot of this aircraft registered in the United States indicated that he wished to land at Inukjuak for a short stopover. Several passengers were on board. I gave him the necessary air traffic services and followed its progress towards the airport, through subsequent radio communications.

It is assumed that a pilot wanting to land at an airport has prepared himself and knows the length and orientation of the runway, as well as its constitution (cement, asphalt, gravel, grass, sand). These are absolutely essential information, like ensuring that there is enough fuel on board the aircraft. This makes the difference between an accident and a successful landing. I doubted that Inukjuak, with its soft sand runway, was suited for an aircraft like the Beech 200.

Being a pilot myself, I was uncomfortable to ask him if he was aware of the characteristics of the Inukjuak runway, because this was such basic information. Moreover, having no experience as a flight service specialist yet, I considered unimaginable that in the early days of a new career, I had to deal with a pilot that was not adequately prepared, and would soon put his life and the lives of his passengers in danger.

I kept on thinking that if the pilot was responsible for this type of aircraft, he must have had hundreds, if not thousands of hours of flying experience. It would be like saying: “Don’t you think that the plane is too big for your abilities?

The aircraft was now on final for the runway, a few miles away. I decided to ask the fateful question: “Are you aware that you are about to land on a 2000 feet soft sand runway?”  The pilot softly said: “OK, we’ll do a missed approach and will head somewhere else. Is Kuujjuarapik acceptable for us? “I answered positively and in the following seconds, the airplane overshot the runway and headed southward for the next airport.

From that day and the following decades, I vowed to never take anything for granted. When in doubt, action is worth more than inaction…
