Wow NASA way to go, steal ideas from the past and make them yours.

Boeing’s got it right. The top one with only one engine has no redundancy in case of an engine failure, and the bottom one from northrop grumman has a ridiculously small area in the middle for two huge wing spans to meet and join.

The tube type aircraft has almost reached the limit of it’s capacity and the flying wing is inherently stronger with a higher load lifting capacity and could theoretically carry more than 1500 people with luggage.

Evac procedures could be overcome by allowing egress through the top of the aircraft and sliding down the back over the wings… conversely, the central spar or main wing area could be strengthened and the wings be allowed to sheer off in an accident type event in order to preserve the integrity of the main cabin.

I don’t believe that’s the case. The Boeing X-plane has been reported to be in development as a passenger airliner. I’m sure they’re taking evacuation capabilities into consideration.

the second picture is for cargo only
becuase every aircraft has to be evacutated in 90 seconds in every constelation of 50% of all evacuation doors are open

this is not possible in the 2nd picture models.. so it is only for cargo
