Oh and 1 donkey over the ocean @ $$$$$$$$$$$$$$$ a pop, DUMB.
May have been true a long time ago but not these days.
You may be interested to know that when the USN put out the requirement for a new trainer to replace the Buckeye they specified it must have two engines. BAe felt this was wrong so put in a non-compliant bid with a modified Hawk. As part of this process we set about educating folk about the modern realities of multi engined military aircraft. As you know the T-45 eventually won in a fly-off against the Alphajet (a twin)
Incidentally the first Tornado lost was due to a double engine failure as was the first Eurofighter and the first Alphajet.
