Gee....no Pilot Access doors...hmmmm odd thing that. The Captain is supposed to be the last person off a sinking ship right? "After you Bubba! Now Coey...do let the nice Man go first as he is a passenger, Lad!"
With itty bitty tires like the ones on the mockup....no risk of this thing ever working off other than steel decks or paved aprons, taxi ways, and runways.
Even then...it will take a strong deck to support all that weight on such a small footprint.
How's the gear doors going to like lots of mud and snow stuffed into them?
I know Bell has thought of all this as they put this concept together....right?
