I'm currently doing 6 months of ground school training and I'm the only rotary wing student and have to share a classroom with 15 other fixed wing brothers

. As you can guess helicopters get quite a bit of stick from our plank flying brethren.
I now think I've run out of my stock of comebacks to their jibes so I'm looking for some of your all time favourite comebacks to plank flyers who don't quite understand helicopters.
