Perhaps, but most of the photo evidence that I've seen of
laowai pilots flying with the PLAAF shows them in or near trainers like
this.
And what're the Chinese going to learn that they don't already know? Getting a few pasty faced Brits isn't going to give them the keys to the castle (assuming they don't have said keys). These guys are idiots and deserve a peepee schwack for a remarkable lack of judgement, or at the very least geopolitical awareness. But the reporting about them, and t
he notion that a guy who has flown a Jaguar is helping the PLAAF gain an asymmetric advantage, is overstated.
