Boening SOP's.
I find it strange that we never seem to learn from the past and keep repeating the same errors.
Many years ago there was a famous 707-436 accident at LHR (G-ARWE) when they left an engine in gravel pit and landed with a long flame from the fuel supply as the Firewall Shut-off was still open. The Captains name was Taylor. The airplane was destroyed by fire and, unfortunatly several lives were lost and a Flight Attendant lost her life trying to save those few remaining in the smoke and fire filled cabin.
After that BOAC made major changes to the SOP's when Boeing said they would disown the airplanes and the operation if they didn't do it the Boeing way!!
Here we are, once again, going down the same road after management thought they were better than the manufacturer. Fortunatly, this time, there has not been any loss of life.
