Pretty amazing the pilots managed to pull up again.
Close call on carrier landing

Damn good flying and training. I suspect a change of underwear and flight suits was required afterward.

Damn good training then.
I feel bad for the 8 crew members injured by the backlash of the cable snapping. The report blamed maintenance failure to correctly reset a valve, but at the same time it said it is not easy to realize that mistake because of the design. Kind of hard to believe that that failure then has not happened before and they were unaware of it.
It just occurred to me that the second camera shot from above is probably being shot by a person. At first I thought it was a surveillance camera mounted somewhere, but the way it follows the airplane and then zooms in makes me think they must have a camera person recording every landing.

That is correct. I always hate watching a US military plane crash. These days you won't get a replacement. I was so happy to see that aircraft rise up into the air again!
This was last weekend - what happens when you don't get your valving right. Backed up traffic for many miles and hours.

Yep - prop planes are instructed to go full throttle on touch down and the jets are to go to full military (no afterburners) for just this reason, as well as for a missed trap (catching the wire). Missing the wire is not unusual and the planes have to be prepared to take back off for another go at it.
The dangerous part of catching a wire and then it breaking (other than the obvious whipping wire) is that you have slowed the aircraft speed and taking back off can be problematic. And if you do hit the water you have a 30 mph big azz boat trying to run you over.
This video is pretty amazing. It shows the autopilot kick in on a falling F-16 when the pilot goes unconscious because of G-force.

Good article. I didn't realize the auto-GCAS technology existed in the military. Makes me wonder why this technology isn't implemented on commercial jets. Probably for cost reasons.
On second thought, if drones can land on carriers I guess this technology must be pretty mature.
It used to be called ACLS (automatic carrier landing system) and has been used for many, many years in one form or another. I am sure that the accuracy of today's systems are much more accurate than those of yesteryear.
Approximately the same thing happened to an F-22 test pilot a few years ago during some extreme maneuvering tests. He didn't make it. I wonder if that accident was a motivating factor for developing this system.
Auto-landing controls are a separate category.
On commercial aircraft, terrain avoidance is handled by automated warnings, but the pilots themselves respond. This has never been an issue that I know of because commercial aircraft don't do 8 G's, and have two crew members. There have been cases of pilot loss of consciousness on aircraft with autopilots (the worst was a commercial airliner in Greece that lost pressure suddenly, resulting in every body passing out), and they just flew on following the autopilot until they ran out of fuel. Solving that is more complex than just avoiding the ground or performing an auto-landing. Even the carrier system depends on the aircraft being guided into initial alignment and receiving the signaling from the carrier.
