The fire from the video looks to me like it's most likely from a magnesium alloy wheel after the tire blew. A pilot in the F-4 squadron I was with lost hydraulic power and was forced to use pneumatics to land. He missed the hook for the emergency arrest, and was applying pneumatics to brake the plane. But the right main wheel locked up, blew the tire and started trailing a magnesium flame. Tower told the pilot he was on fire. The plane was drifting off the runway. The pilot elected to eject, but the RIO had already unstrapped. Pilot was okay, RIO killed, plane stayed on the edge of the runway, the magnesium wheel ground down four or five inches.
