Air travel in crammed tiny metal and composite tubes for long periods that need to be turned around in a jiffy thus may be subject to deficient cleaning is most def a vector. For the long term it would great to design airplanes that have a inner tube component that can be pulled with the nose moved up. Basically a bus without an engine. Cheap, can be driven around the unending concourses, can be sterilized properly because an extra one can be used. I think it may even end up being a time and money saver, boarding is a non compressible and long part that could be a lot faster from the sides.Not sure it'a 10X...
