BIK. Well, nasa did say:
"......with those parameters, or close to it."
nasa is prone to dreaming spells and I thought the lovely little Connquest 1 came rather close - even if it won't legally accommodate nasa's caste of thousands.
Bums in the nose locker of a Cessna 400 series. What a great idea....... I remember a passenger in the pod of a Cessna 185....... but that's another story altogether.
What nasa wants is a Reims Cessna 406 (or whatever it's called), pressurised, with lovely -34's. I seem to recall that had a modified Titan fuselage.
Or a pressurised Bandit with bigger donks. Think that already exists, shorter fuselage - an Embraer Xingu?
Or Blue Haulers lovely King Air 350!
nasa. How about a Britten Norman BN2A MkIII Trislander Bongo Van? I heard some nut was thinking of adding two turbines (or was it V8's) to the Trislander fuselages rotting away in Australia somewhere. Be right up your alley!
