'Courtney Mil' I do not see 'conflicting statements by 'Engines' as you say. As for my comment about 'sparks'. Metal on Metal (or likely THERMION covered Metal) will make sparks - no matter how gentle the contact. Have a look at night carrier landings to see the sparks fly. And why do you protect 'Low Observable'?
I thought I had made the point earlier about "...indicate serious metal work - wear to the deck and the hook shoes." This is a given. A4G maintainers either of their own accord through inspections or at request of deck gear chaps, would blunt the steadily sharpened A4G hooks. These hooks have a finite life also; to be replaced as required. Have you seen up close the state of a 'cats n'flaps' carrier metal deck?
I'll find a night DL video for youse..... No need to watch all this otherwise excellent video - the night deck sparks de hook are only at beginning - after that - fun/games.
