A car and a plane are two different types of machines with two completely different types of requirements. Cars need to be sturdy and solid, planes need to be as light as possible. That makes them fragile.
Trying to make one machine that can do both will result in a machine that can do neither well.

This lesson was learned many times in the past, but some people are too dumb to realize that and keep trying to make a bad idea work.

My bet is that they are more interested in attracting foolish investors than actually building the machine.
