Something's been bugging me. We know 909 reported a problem with no4 but something else caught them out. There was an earlier eyewitness saying it was no3 - has this been completely proven to be false? There were reports they were working on 1 or 2 engines prior to take off.
Had a flight in Aluminum Overcast years ago and I'd jump at the chance to do it again. All passengers know the risk. Such a tragedy for all concerned.
