Hi,
Here is a little addition to the site for today, following a virtual flight made over Peru with the flight simulation software Microsoft Flight Simulator (FSX). Some modifications have been made to the screen capture in order to obtain the present result. The picture nonetheless reflects very well the atmosphere during that flight. For those who would like to know what software was used to produce the clouds, it was only FSX with ORBX 5 selection in the weather section. This selection always manages to offer an interesting sky.
