wwii

I got a nice little booklet in the mail today, a 1952 UK Government paper on "Condensation Trails From Aircraft". It contains some interesting discussion on the science of contrails and experiments that were carried out during WWII to try to advance that science. Contrails were a major concern...

Very interesting video. It's quite genuine (Although it's actually from 1923, not WWII), and shows a plane laying down a vertical curtain of smoke, with the caption "To protect the bombing plane the Air Service can lay a smoke curtain". It looks like the curtain of smoke would be laid down...

so says TankerEnemy - I ran across this just now and am just speechless - it's not long - less than 3 minutes.... Source: http://www.youtube.com/watch?v=N304lzfVgN8
