THUNDERBOLTS: Final Batch 6. Helicopter.
This ended up being based on a Blackhawk but there were many variations prior to this (maybe one day I'll upload them). It had to stay within the realm of believability, and with vehicles you can easily slip into sci-fi. So I stayed grounded, and......stealthy! Here is the final plus an earlier concept. Apparently it featured well in the film I'm happy to say.
