A321 AAIB Report: Mayday/emergency landing due to fuel additive error
As reported on the BBC:
Plane engine stalled and caught fire after 'engineer's fuel error' (there's a link to the AAIB bulletin).
An A321 taking off from LGW on 26th Feb had engine problems at 500ft, leading to a Mayday call and emergency landing. Fortunately not a bad outcome, but it must have been an exciting few minutes.
