Ponder for a moment the ejection envelope...(under the skyhook apparatus).

Ah Da SkyHooks (famous Oz band in the 1970s) but also plenty of HOKiness on this forum searching on dem SKYHOOK:

Other than the Goblin fighter trapeze in the B-36, this might well exceed it in danger. At least with the Goblin if it missed the hook, it had enough altitude to recover.

Not so here!

It's no more dangerous than a STOVL landing at sea today, in terms of fuel & altitude for recovery... well, maybe just fuel :roll:

Ejection envelope in any kind of sea state apart from ‘calm’ would be interesting to see — even with a stabilized crane system. It would also be interesting to understand the degree of precision required in both the crane and the cockpit for ‘capture’ of the aircraft by the crane.

The F-35's ejection envelope is 0/0 with auto-eject in STOVL mode.

Dude, you have an obstruction near or above the seat’s pathway out of the jet (the crane). You also have a very restrictive wind envelope given the turbulent flows that are going to come off of the ship, which will further complicate safe ejection probabilities.

I would also point out (wrt f-35) you have the AAI/doors in the fuselage structure where this device would nominally capture the jet. Reminder at the link —
