he was at very low altitude, struck by lightning, in a completely glass cockpit plane. You don't "call your wingman" in that situation, you decide and you do. He didn't believe the plane was flyable, and in those conditions I don't think he had enough time or separation from the ground to make sure.

He was doing an instrument landing at the time. When the ILS switched off, he automatically aborted the landing as trained. This is a go–around, so you apply TOGA thrust, point the nose up, level the wings, raise the gear, and climb to 4000’ or whatever is the correct altitude for the TOGA procedure at the airport you are at. He was already 1200’ above the ground and climbing when he ejected. He was in a perfect level climb, he just wasn’t looking at his standby instruments and so he lost situational awareness for a few seconds. Glass cockpit or not, the standby instruments and fly–by–wire system were completely reliable in spite of the lightning.

  > He was doing an instrument landing at the time. When the ILS switched off, he automatically aborted the landing as trained. No, if you read the report, he was on final and, for whatever reason, instead of continuing the landing procedure he decided to change the aircraft mode to vertical landing and this caused the helmet to glitch.

    The redacted version of the report does not state that there was any causal link between switching to SVTOL and the failure of the HMD. Only that the HMD happened to fail shortly after he switched modes: 95. Approaching the final approach fix, the MFL made the radio call to convert the flight to Mode 4 (STOVL) and slow the flight to 150 knots in preparation for the 100-knot slow landing. This was the last radio call Swede 12 heard from Swede 11. [Encl (17), (19)] 98. MP reported his HMD flickered shortly after converting. Near simultaneously, a momentary caution displayed in his HMD that he perceived to be engine-related and then the HMD flickered out. While MP considered missed approach options, the HMD came back. [Encl (17)] And from the evaluation: 19. Primary factors contributing to the mishap can be traced back to event that occurred at 13:32:05. This event induced failures of both primary radios, the TACAN, and the ILS. [FF 100, 101, 126-129] 20. Additionally, it is probable that the HMD and PCDs were not operational for at least three distinct periods. [FF 98, 103, 104, 106, 114, 132-136, 141]

  That's definitely not what happened and not what the report says. Also, this is a STOVL aircraft, and I suspect the procedures are completely different.
