As a skipper on the 380 I feel well enough qualified to comment on this. The simple fact is the A380 on 3 engines is as safe as any modern twin. This crew made the correct decision to continue the flight given the amount of information they had. For those that worry about fuel contamination and further failure they are using an outdated argument. The 380 has telemetry on a level greater than a formula 1 car and every plane is monitored not just by Emirates but Airbus and Engine Alliance, the fuel pump problem would in all probability be known about before the crew got any warning.
I don't expect people who have not flown this aircraft to fully understand its capabilities and it's huge redundancy in every department ( including engines!!) but the comments from the few people on here about this being unsafe are just ludicrous and show a complete lack of understanding of 4 engined operations.
