How can they be identical if one has ram jets and the other
has a T/R?
I'd be very interested in knowing how they supply fuel to
the ram jet engines on the tip of rotor blades.
Not sure what is meant by travel distance and lifting while
*stationary* in the air. Does this mean they really didn't
go anywhere?
