Warbirds: B-25 Mitchell - Tonnerre sur Tokyo — Warbirds: B-25 Mitchell – Tonnerre sur Tokyo

This comic book, published in 2023, is the third in the Warbirds series, published by Editions Soleil.

On April 18, 1942, a few months after the Pearl Harbor raid, sixteen B-25B Mitchell bombers took off from the new Hornet aircraft carrier for a surprise attack on five Japanese cities. The mission was known as the “Doolittle Raid“.

These machines, which were not designed to operate from an aircraft carrier, would not be able to reach their targets and return safely to port for lack of sufficient fuel. All the pilots were well aware of this, and volunteered.

The fleet of sixteen aircraft, commanded by Jimmy Doolittle, successfully achieved its objective of confusing the enemy and showing that Japan remained vulnerable to surprise attacks. The Japanese wondered how it was possible that American bombers could have reached and hit their country. Where did they take off from? They know that the B-25 Mitchells were not designed to take off from an aircraft carrier, and that they were incapable of landing on one.

The genius of the operation laid in the combination of a number of highly risky decisions which, taken together, took the enemy by surprise. Firstly, as it was impossible to land the planes on the Hornet, they were installed with a crane, knowing full well that they would never return to the ship.

In addition, the captains were trained to take off over distances unthinkable for them, using a technique pushed to the extreme. The ship sailed at high speed into the wind, improving the headwind component so essential for such perilous maneuvers.

The pilots had to be extremely skilful to keep to the departure trajectory on a platform that moved from left to right in the middle of a storm. Buildings on the Hornet’s side had to be avoided at all costs, and the available gap between the wing tip and the ship’s tower was no more than two meters. Despite all the obstacles, all the B-25s managed to take off. It was to be a one-way mission to Japan.

Doolittle piloted the first B-25 to take off from the carrier. He had only a very small portion of the deck to work with, as there were still fifteen other bombers waiting their turn to take off. The second pilot to leave the deck narrowly avoided a water landing, as the aircraft sank slightly and a landing gear wheel touched the water. But the plane gained just enough speed to stay airborne.

Bombers and crews suffered different fates once the bombing raids on Japanese targets had been completed. The authors conclude: “The raid destroyed 112 buildings and killed 87 people, in about 6 minutes. […] The destruction of 15 of the 16 B-25s, unable to reach Chinese airfields for landing, was nevertheless to be deplored, the 16th B-25 having landed safely in the USSR. Also to be deplored was the accidental death of three airmen (planes 3 and 6) and the capture of 8 others (planes 6 and 16) by the Japanese, 4 of whom never returned home, 3 having been executed as “war criminals” and the 4th having died in captivity. Worse still, the Japanese took revenge on the Chinese, who had helped all the surviving airmen, by organizing the massacre of some 250,000 civilians in the Zhejiang and Jiangxi provinces then under their control. This was to leave its mark…”.

Landing and takeoff tests on an aircraft carrier, the Forrestal, were also made decades later for a C-130 Hercules. I tried to repeat the experience in flight simulation. The flight can be found in the “challenging virtual flights” section of my blog. As the Forrestal is not available in virtual mode, I used the aircraft carrier USS Enterprise.

MSFS 2020 map for the flight 3U2 to C53 in United States

The challenging virtual flight is from Johnson Creek Airport (3U2) to the Lower Loon Creek Airstrip (C53) in the United States, using the MSFS 2020 flight simulator. The software map shows the type of aircraft chosen, a CubCrafters X Cub on floats, as well as the trajectory over the Idaho mountains.

The idea of using an amphibious aircraft for this flight is a bit far-fetched, but the goal is to make the pilot’s job a little more difficult by adding weight to the aircraft.

Johnson Creek Airport (3U2) is a creation of Creative Mesh. It is charming, with tents here and there planted near the planes. The runway is 3480 feet long by 150 feet wide. It is oriented on a 17/35 axis and still quite high at 4960 feet above sea level (MSL).

Given the departure altitude, one must not forget to adjust the air/fuel mixture so as not to lose power on takeoff, especially since there is a mountain at the end of the runway and the floats increase the weight of this small aircraft. The air is also thinner as the flight takes place in summer and at a high altitude; this represents another obstacle to the aircraft’s performance.

The mountains near the runway present a significant obstacle. The virtual pilot must use the best possible angle of climb without worrying about the route recommended by the GPS. The flaps are kept slightly extended during the initial climb.

Once at a safe altitude and back on the GPS suggested route, the view of Idaho’s spectacular mountains is more enjoyable. Throughout the climb, the air-fuel mixture and altimeter (“B” on MSFS 2020) have to be adjusted.

An altitude of almost 10,000 feet ASL makes it possible to fly over the mountains without risk of collision.

At the right moment, when the small surrounding airports and the river appear on the GPS, we leave our GPS road, until now in straight line, and we align in the valley to fly over the river until our destination, avoiding the surrounding mountains. In the photo above, the descent has already begun, with a necessary gradual adjustment of the air-fuel mixture.

We fly over a first small airport. The picture above shows the planes parked on the runway of Marble Creek airport (ID8), which dimension is 1160 x 20 feet. For those which would be interested in trying a landing there, the orientation of the runway is 03/21 and the altitude of 4662 feet MSL.

On the way towards our final destination, we also fly at low altitude over the Thomas Creek (2U8).

The mountains on either side of the river require close attention, as the poor performance of a small aircraft equipped with floats does not allow for easy correction of navigational errors.

By the time the runway suddenly becomes visible, the plane will not be on course but 90 degrees off the ideal course. It will be necessary to quickly turn left into the valley, make a fairly sharp 180-degree turn to the right to avoid the mountains, and then get back on course to land. It is only at this point that the landing gear will be extended.

The photo above shows the aircraft on final for the Lower Loon Creek dirt and grass runway (C53). It is located at 4084 feet MSL and is only 1200 feet long by 25 feet wide. Note that the approach should be made on runway 16 when possible.

As always, a stabilized aircraft on final makes landing easier, regardless of the conditions.

We park the plane and rest a bit. Today, there is no one else here. But that’s not always the case in real life, as this video of a landing at Lower Loon Creek shows it.
