so erm... not sure if this is a bug or a problem with the arena settings, but ive noticed everytime ive flown the C-47 and dropped troops, they seem to hit my tail and nock it right off, at first i thought well maybe i just hit a building so i tried it while on the ground and not moving, drop troops, bam off goes the tail.
