Could one in theory use old fuselages from retired planes for cheap alternatives to ground transportation? The reason planes are retired is because they can no longer handle the stress of constant pressurization and changing expansions from changing altitudes. So if one were to say, take these old fuselages and throw them on some rails or a bus, couldn't it prove a cheap and viable alternative to creating a whole new body? Seems relatively simple from a manufacturing level.
Perhaps there are laws restricting or banning this kind of re-use. but a quick google search reveals that aircraft boneyards frequently re-sell/use vehicle parts. So why not use the fuselage for ground transport? Is it simply too expensive?
