Another mystery

Everyone likes to get away with things.  As Austen would say, it is a "truth universally acknowledged."*

For instance, programmers put Easter eggs in products.  The first PostScript Level 2 Dataproducts laser printer (from the mid-90's), prints out a lovely picture of the lead engineer's wife in a sweeping floor-length ball gown, if you fiddle the buttons right.  I had to dislike that guy, because his PS2 product beat mine out for the being the first by two weeks.  Also, my Easter egg was lame by comparison.

During the Korean war (sorry, "Police Action") air cargo crews used to smuggle beer and other contraband in-country, hidden in things like empty fuel drop-tanks or bomb casings.  They HAD to do this because the local Korean employees were also indulging in a little creative commerce.  Legitimate beer arrived on base in wooden crates full of beer cans.  The local staff would pop the crates on top of a washtub, and hammer stiff wires down through the cans, liberating the goodness inside without opening the crates.  So there was a shortage of legitimate beer, naturally leading to a supply-and-demand problem.

Now if there's one thing for which there's always been, and always will be a guaranteed demand, it's a scantily clad MOTAS.

Which bring me to this picture.

"DANGER" certainly.  But why is the GROSS WEIGHT blank?  She doesn't look over-gross to me, even for the 60's.

The "why?" need not be questioned, of course.  But what I always wondered, and never got a rational answer to, was the "how?".

This was almost certainly a military airbase (if I had to guess, I'd say it's El Toro) or a NASA facility (lots of which are located on mil bases).  It's night.  It's on the flight line.  There are fences and there are armed guards.  It's the height of the Cold War.  She's definitely out of uniform.  That plane resembles an A-4, which has barely enough room for the pilot and a toothbrush, so she didn't arrive in that.

I think I'll submit this to Car Talk as a Puzzler.  Maybe they can crowdsource a good answer.

*Speaking of Jane Austen:  Because I sometimes watch The Big Bang Theory, I was pointed to a web video production of a contemporary take on Pride and Prejudice at The Lizzie Bennett Diaries.  90-odd episodes, and pretty hilarious so far (after 25 episodes).  Recommended.  Kaley Cuoco's sister plays Mary (who is a cousin instead of a sister in this adaptation.) hence the connection.
