That jumbo lost *two* engines, not one.
And an airliner losing an engine 5 seconds after take off is not
neccesarily screwed. In fact, even losing an engine during the take-off
run, but after V0 (I hope I have the number right, I am not a pilot) or
decision speed, the A/C should have enough power to continue to
accelerate to V1, rotate and take off and climb out safely.

If engine out happens before V0, the crew brakes to a stop.
