Can a missile retarget to the heat from the firing aircraft's engines? [closed]

I have heard that modern war planes utilize missiles which are directed to the heat of the enemy aircraft's engines.

Can a missile, shot by a fighter helicopter or jet, target the heat of the engines of the aircraft which fired it?

• Not really since you have a missile lock before firing. – Ron Beyer Feb 2 '17 at 14:18
• You mean, an accidental 'loop around', or something compared to radar targeting, where the reflection of the IR signature from the engines is reflected off the target? – Sanchises Feb 2 '17 at 14:18
• Are you asking if a missle-launching aircraft can accidently shoot itself? – Dan Pichelman Feb 2 '17 at 15:16
• @RonBeyer But what happens if a friendly aircraft happens to cross the missile "lock-path" when it's already in the air and chasing a target? Infrared missiles IMHO don't have IFF. – jklingler Feb 2 '17 at 15:55
• @RonBeyer - Not really since you have a missile lock before firing - Not always. See: LOAL (lock-on after launch) – Hephaestus Aetnaean Feb 3 '17 at 6:54
