The F-35 is useless for long engagements, dead if it gets into a dogfight, and can't fly near thunderstorms or it might explode.

This is assuming it doesn't suffocate its pilot to death, because Lockheed still can't get the oxygen system to work properly.

The finest plane $350M (and climbing) can buy (for the F35-B variant. The A variant is down to "just" $100M or so.)
