I would hope that Boeing will come out with some better advice, following a loss of electrical power, than has been posted on this forum by speculators!
At least people are offering advice for debate... good or bad... rather than fatalism
Reminds me of a story someone related to me many years ago... of the crew of Middle-Eastern carrier faced with what seemed like an unsolvable problem. While the guys in the front seats prayed to their god, the Flight Engineer of non-Arabic origin kept on trying to come up with a solution (I believe he finally did). ok ok.... maybe the prayers helped...
And speaking of pitch/power solutions... If a certain DC10 pilot hadn't practiced all-hydraulic failures in the sim after another DC10 experienced problems... a few hundred passengers might not be alive today to tell the tale of his heroism.
