Nearest I ever came to being really close to one, aside from "At Home Days" behind a fence, was last year at the Palm Springs Museum in Ca. Think it was an F4D. Static a/c minus engines in the pound getting ready for a refurb.
I discovered the port side retractable ladder. Of course I had to climb up and have a look inside. And of course the Missus had to have a look too. Got some ear ache when her pants got dirty but it was worth it. Wonderful to walk around it and "feel" it. The a/c has so much presence.
Was the same ladder present on the F4K/F4M ?
I can highly recommend that museum if enyone is over there. A very nice TBM is also on display in FAA markings.
