We had a AN124 delivr an anssembled spare GE90 to our hombase in VIE on time, when it went back out everybody was watching to have a look see how the thing flies..
So having all the crowd looking she lifts of, starts a right hanf turn out of RW29 and BANG!!! -> Flames and smoke out of engine Nbr.4 and back she was in a few mins.
So they brought in the spare engine and a crew with another one and the next day we watched again the now two AN124s going out .. and BANG Nbr. 2 turns back this time for another problem
i DO hope THAT one is better in therms of reliability
