Drones are not cheap.
They are onoy cheap in comparison to the fighters and bombers that they are competing with.
I note that the Air Force is training more Drone pilots than regular pilots.
Drones have to be viewed in terms of what they can and can't do.
They can turn inside a fighter, they don't have mothers and they can loiter without bladder relief on the job a long time.
On the other hand, they crash about 3 times as often as manned planes, they can be meconned or suborned, and they are perfectly terrible at checking their own six.
If we were using drones against a more modernized enemy, the drones would be very vulnerable to getting shot down by fighters.
I disagree with the documentary about the F-35 which seems bound to disappoint.
But the F-22 is a for real world beater.
They are also right about the F-15 surviving every dogfight it has ever been in, but that its equal is in the marketplace now.
