maybe I missed something but the person you are writing about didn't say he took a 757 into aspen, he was talking about an early lear jet. He said it was in the early 70's and the 757 wasn't out by then.
On these forums I take people at their word. After all the accusers may not be telling the truth either and you really don't know.
We could ask questions like: what is the dead dog switch?
or
We could ask questions like: how many holes are in the speaker grill over the captain's head on a 737?
Would that prove anything?
And if one person says something and another disagrees, it may just be the differences in ways of doing things in one airline's ops manual over another.
