Further to my last post. I have re-read Annex L to the BOI Report, titled 'Search and Rescue Report on the 2 X F15c Accident' and dated 25 Jun 03.
It is a very detailed summary of events and makes no mention of the USAF passing on information about an IR signature. Furthermore, the report makes it very clear that there was considerable confusion as to where the aircraft might have crashed and that the search area was only refined after a replay of the radar data.
