Mug Ugly X 2!!
i am not an aerodynamic engineer by any means, but from what i have seen--there is a beauty to every GOOD flying machine i have seen. the top of the list being the B757, now being overtaken by the B777. and from what i read, the aerodynamics are rich in those two good looking aircraft.
and when i first saw the MU2, i knew right away i did not want to fly that machine--ever!!! even before i had learned what little i have about aerodynamics. on the ramp, we would call them, "four trash cans strapped together."
and the fact that when re-fueling it, there could only be a 25 gallon difference when putting fuel into the tip tanks, struck me as a sign of instability. the lear 24 could take a 50 gallon spread, and it had a reputation as a pilot eater.
i only personally knew one individual who had flown the MU2 and it had almost killed him in a crash.
an aircraft to avoid in his estimation.
