Shortly after WW2, they had a program (I think it was just called Project thunderstorm) where they had a squadron of modified birds with extra air data sensors and a second radar to fly through midwest thunderstorms.
Interesting. I have looked this up and read a little.
The Thunderstorm project used a stack of aircraft flying on the same heading at 5K, 10K, 15K, 20K and 25K. Radar collected data that built a top-bottom picture of a thunderstorm. P-61Cs were available, had very strong wing structures. I think the aircraft at the Smithsonian and Dayton are survivors of this project.
