Thanks for the link. A longer quote on the nature of the emergency:
After launching from runway 23 of Willow Run airport (YIP) in Ypsilanti, Michigan as part of the Thunder Over Michigan air show, the MiG-23 pilot executed a right turn into a so-called “banana pass” – a low-level knife-edge pass along the runway.
As pilot and aircraft owner Dan Filer banked out of the pass, he noticed the Soviet-made jet’s afterburner did not ignite, after which the MiG began to lose airspeed, the NTSB says of Filer’s recounting to investigators.
In response, Filer adjusted the MiG-23’s variable geometry wings into the fully forward position of 16° sweep to maximise lift. The former US Navy aviator was in the process of troubleshooting the problem, according to safety investigators, when the rear seat observer argued for and executed ejection procedures.
