What happened is rumoured to be as follows:
1. 737 pushed back from stand at Dublin. No 2 engine wouldn't start. Decided to go anyway as chances of another engine failure have to be slim, and besides the reduction in fuel burn would save the company money.
2. About and hour into flight it was realised that kgs had been confused with lbs when ordering fuel, and there was insufficient to reach destination.
3. Captain did the maths on speed/distance/wind (no 1st Officer to cross check as the airline was operating its new single pilot policy on this flight which further cuts costs in terms of salary and weight carried in the aircraft, offering yet lower fares for no great drop in safety), but forgot that 300/40 means the wind is from 300 at 40, not blowing 300 at 40.
4. A/C glided into Dublin from around Liffy and taxied on stand. The "1 hour" the engineer was talking about was the amount of time of the pilot had had off so far this year.
Much tosh on this post, song and dance about nothing. Had this been a full cost carrier, say Aer Lingus no doubt must posts would be "well done to the boys on the flight deck". Because its a low cost it must be due to a f*&£ up.
