I think he's talking shite.
It seems odd to me that he would be admitting to an issue which didn't exist, which pilots have themselves described.
It sounds reasonable to me and I bet I'm not the only person to have found themselves face-planting the ground when running so fast their legs can't keep up.
I am more intrigued with what happens when we have an F-35 with a damaged wing and a damaged engine. How we solve that one when engines need repairing in Turkey, the wing needs repairing elsewhere. Do we turn to FedEx in time of war?
Seems we've put everything else in America's egg basket. It is utterly ludicrous to put the defence of Britain in foreign hands. Oddly it seems the Take Back Control brigade are the ones most in favour of that.
