“US officials familiar with the situation later confirmed off the record that an F-15E had been brought down and the Pentagon was scrambling to find the crew. There was no official comment from the US military about the incident.

Subsequent footage filmed in Iran showed a US C-130 Hercules and HH-60 Pavehawk helicopters flying low and at one point refuelling together, amid fresh Iranian speculation that the plane crew may have ejected and survived.
Justin Bronk, an aviation expert from the Royal United Services Institute (Rusi), said the use of the specialist helicopters “suggested a combat search and rescue mission is under way to locate and extract the two aircrew from the F-15E”.

A social media account claiming to be linked to Iran’s Revolutionary Guards posted a picture of an ejector seat in a desert landscape, which appeared to be consistent with the ACES II type used in F-15Es. Bronk said: “If genuine, it would suggest that at least one of the two aircrew did eject safely.”
