Many, many years ago in my blue phase I found myself on the Rock with a spare forenoon. It was a fine day, so I went to the top.
A cruise ship was in port. Some of the passengers were also enjoying the view from the summit.
Elmer, in plaid shorts and a mildly clashing check shirt was standing next to Ethel who was dressed entirely in beige.
They were both facing South, looking out over the water. Ethel turned to Elmer and said "Gee, Elmer, what's that big island over there?"
One recalls a trip from Edmonton to Elmendorf AFB a few years ago in a 'K. About an hour prior to top of drop Flight engineer looks out of the port window and asks me:
"what's the name of that big lake?"
A: "The Pacific Ocean"*
Or the RAF co-pilot flying over the Alps asking "Which one's Everest"
Or the RAF co-pilot on another fleet, after hearing the above story, whilst flying over same said mountain range, asking, once the laughter had died down "Yeah, but which one
is Everest?"
Or the RAF aircrew (can't remember crew position - probably co-pilot) stating, after getting out of breath playing
beach volleyball, "it must be the altitude."
