Going back to Schiller's point about approach end engagements, they can be planned for FJs with problems such as hydraulic problems where nosewheel steering is lost. Normally means a reduced landing speed though. The problem is the accidental ones, particularly into a barrier....
Durin 1991, at Tabuk, Saudi ATC cleverly left the barrier up when they changed runways during night operations. An RAF GR1, during a night landing, engaged it during the flare and whiplashed into the ground, broke her back, ran off the runway and caught fire. The crew, thankfully, managed to eject with minor injuries. The aircraft, ZA446, was classified as CAT4 and shipped home.

Not sure if it ever flew again, but
this is all that's left of her now.
