Ah, yes....the dreaded engine failure in a 4 engine aircraft which, according to the media, is yet another event of earth shattering proportions.
Loud bang.....flashes of flame. Compressor stall...????
These engines are always "on fire". You just can't normally see it and being "on fire" simply means that it's hot in the "cold" section.....it isn't always necessarily all that dramatic.
Most likely a standard engine shutdown on an aircraft with four engines requiring no departure from normal operational changes other than return
.....your welcome.
