BVR: AI aircraft stuck in stall

[Actium]

In a simple BVR scenario with a flight of 4 MiG-29 air-starting in a line abreast formation, the flight presumably attempts to switch to a grind formation. That typically results in some of the wingmen (usually trailing pair) stalling at 130 kts IAS and 21° AoA on full burn until they snap out of it minutes later when a plane finally gets hit. This is not limited to the Fulcrum, but also occurs with the Flanker. Starting with a trailing formation may result in fewer stalled planes. This has been previously reported for the F/A-18. I've attached a track and a tacview: AI_stall.trkAI_stall.acmi
