OK, this happened only once that I am aware of.....
There was a fly-off competition held between two different aircraft designs. Plane #1 flew pretty well. Plane #2, though, flew higher than plane 1, quite a bit faster, had longer range, could outmaneuver #1 basically at will, was cheaper to buy, cheaper to fly, and cheaper to maintain. #2 out-flew #1 in basically every way possible. Both planes were planned to carry a similar sized mission load for the intended role. And yet, despite all of this, plane #1 was selected as the competition's winner. It should also be mentioned that aircraft #1, the winner, also had one serious design flaw as well as another feature that would prove to be a very serious flaw, though it wasnt a fault of the plane's design itself.
Name the planes involved and the reasons for the choice made. Bonus points if you can also state what took place the next time that these two aircraft met again.....
