Been out of the AT system for four years now but I do remember in GASOs at the time was a comment that the VC10K had to carry a LM or an Air Engineer with a Freight Bay Management Cat if there were passengers in the cabin. Also seem to remember this was diluted further to include a Ground Engineer? I suspect that because a Steward was carried he was in the cabin and so he was therefore required to assist himself with emergency egress from the main hold if required - if you catch my drift?..... I also remember that some ALMs were posted to the Nimrod Fleet in the late 70s but it was binned after a couple of years. It did provide a good sin bin for the naughty boys from Lyneham at the time though!
