I believe most, if not all, AF tactical jets have arresting hooks for emergency landings. They would take a field trap for the same basic reasons a Navy jet would, landing gear problems is the one that comes to mind. However, what no one has pointed out yet is that Navy jets are stressed for carrier landings while AF jets are not. If you ever take a look at an F-16's landing gear and an F-18's, you will notice that the 16's looks whimpy compared to the 18's. I have heard the figure of a 1000 pounds extra for the Navy landing gear several times and I buy it after looking at the difference. Additionally, the hook and its attachment to the aircraft is strengthened on Navy planes, all you have to do is look at the difference again.
An interesting side note, not all pilots who fly Navy tactical jets have to qualify at the boat. In the land based VAQ squadrons, the AF pilots (one per squadron, 3 squadrons) do not have to land at the boat. Apparently they did at first but it was considered a waste, correctly so. They tried to get the Marine VAQ pilots waived for the boat a year or 2 ago but that was nixed by higher ups, even though they have not deployed on the boat since the mid 90's.
As for the T-34 shooting down a Harrier in the Falklands, I have heard that repeated by several guys, including a LCDR IP, with a straight face

! As an amatuer historian, I researched the hell out of that one. The best resource I found was a book called
Harrier by a Harrier squadron CO in hte Falklands, "Sharkey" Ward. I got it in England (only available there) and he talks about taking a few shots at some T-34's in and out of clouds and finding out after the war that he hit one, though the shell was a dud. The Argentnians had loaded them up with rockets and machine guns but they never fired a shot, I think one is in England as a war prize.
