Checklist.
I have read some rubbish on these pages of PPRune but never as biased as this one. How far up BA's bum do you need to be, how all and sundry think everyone did a wonderful job etc.etc. My 20000hrs experience says that when I loose an engine cowling I check all engine parameters, and then, dump fuel, if required, and land at the nearest suitable airport. Nowhere in my thinking do I take my customers for a ride around the Southern English countryside, and then return to base. Lets wait for the subsequent inquiry, available to the public, because there needs to be one, a lot of people were very lucky today.
