NSEU, good point about the cargo door, if memory serves me right, that UAL door problem was in 1989, door viewing windows were kept clean for a couple of years, guess it will take another UAL for the windows to kept clean all the time.
Back to the point of elec power, wind up radio's have been about for years, am sure a similar system could be used to power a few ess systems, am sure the passengers would be happy to operate the gadgets!
