I was trying to be more subtle to flush out those whose mind thinks the same way mine does so you and vne165 can share first prize which is a laurel and hardy handshake.

If we assume he parked at the ANG base then there was 10,000 ft of RW21 available. Even if he just made a quick fuel stop at Atlantic there is at least 5,500 ft available.

Could he have been attempting to abort a normal mode takeoff using STOVL. Could the high pitch attitude be explained by attempting to decelerate?

What is the normal range of pitch attitude in the deceleration from normal flight to vertical landing?

Aircraft back on the ground then the pilot ejected when it went off the end of the runway

The plot thickens.
Other things relevant to sustained flight, not so much.

A hot and high airfield with an unfamiliar and slow accel/climb from a STO may have been a factor?

Would be on my list of possibilities.

5300 feet and 90F. That's one Mile High Club you don't want to join.

The firefighters mentioned people in a car (pickup?) hit by flying debris.

I did not realise the airfield was in the mile high club: upload.wikimedia.org/wikipedia/commons/d/df/KABQ_Airport_Diagram.svg

Why the concern about KABQ altitude? Is anyone really suggesting that a normally operating F-35 with no stores can't safely takeoff from a 10,000 ft runway in the prevailing conditions?

(I've been flying in AZ for over 35 years and I do have some understanding of DA)

Assuming everything is in working order, of course not. However, if one plans to use this jet’s powered lift system and that system does not generate the expected power/lift, you will have a problem — the successful resolution of which will be highly reliant upon pilot technique and finesse.

Q is what effect it has on the speed at which you can hit the convert button.

Mode 4 conversion (depression of the ‘Hook/STOVL’ button on the upper right of the instrument panel) happens before you start your engine run up; the environmentals (OAT etc etc) and the predicted lift system performance determine the KCAS at which one initiates rotation, whether it be auto, manual or hotas.

One day there will be a public version of Flight Manuals / NATOPS for answers to a lot of F-35 questions. Meanwhile some nice 'from the front' STO JPGs: https://www.twz.com/uploads/2024/03/...1-1-scaled.jpg & https://www.twz.com/uploads/2024/03/...408-scaled.jpg

"...Once the jet is above stall speed, the pilot presses the conversion button

I still have the source document on file. One way or another it looks as if the conversion was started at a speed that was too low for the prevailing conditions - the video closes the loop and shows the aircraft sinking relative to the altitude in the earliest photo.

‘Conversion’ describes the transition of the propulsion system from Mode 1 to Mode 4 (conventional to STOVL flight). I think the term you’re looking for is ’rotation.’ You might recall that it was/is very simply NRAS — nozzle rotation airspeed — in Harrier.
