Propeller airplanes are not different, in fact real accidents happen with these airplanes. This didn't stop such airplanes from being widely used. Given a well

  I am horrified by eHang's propellers. Can't they add some sort of guard around them or move them above the cabin? I can't stop thinking that even passengers would run into them frequently when stepping on or off the thing, not to mention loss of control situations..

  Well yes, and airplanes only operate on airfields with generally carefully controlled access, and still those accidents happen. Now, with airplanes there is really no other option, but with a drone one can easily place the rotors above, rather than below, the passenger cabin (which also gives better stability). The eHang 184 is truly a horrendous design in my opinion, and I am puzzled why it is seriously reported about.

      Very interesting. I’m not sure whether that fallacy applies. Hard to find authoritative statements on it. There is a thread on aviationexchange where some say that an underslung helicopter is actually more stable than a conventional one, but I haven’t been able to verify this. With a multicopter, the situation might be different still.
