Sorry Bermondseya but you're mistaken that this hasn't been covered elsewhere. You are of course entitled to join the 'debate' - everyone else has- but may I suggest that you do 'trawl' as you will discover the answers you seek. As a BA 747 pilot I am aware of the sequence of events. BA pilots are not debating this on the BA BALPA forum as it is simply a non-issue. An event took place and the crew acted as they are paid to do. There have been another couple of long threads where my 747 colleagues have politely tried to explain to the pilot/spotter community at large. This has turned into another such thread.
Off to LAX now, & noting that our procedures
still haven't changed
