It is obvious there was "procrastination" in the cockpit
Bloggs,
I just timed myself setting an imaginary park brake, making an imaginary PA, asking my FO to identify and then running memory items, then having a very brief imaginary chat with ATC before asking for the Evac checklist. I stopped the iPad timer when the Evac command came. It was 12 seconds slower than what the BA crew did.
I would recommend anyone reading this to do the same in the calm quiet environment of their lounge room, without additional cargo fire alerts, startle effect etc.
For me it was an eye opener because I know from experience that I would have been graded nicely in the sim yet 12 seconds is a long time to be sitting in 25a looking at ( and probably feeling) a large fire three feet away.
Regardless of how contributors to this thread view the BA crews actions I suggest you run this little exercise and see if it changes/ tempers/ reaffirms your current assessment.
I am certainly throwing no stones in their direction.
