Reminds me of a time around 1968-9 when I wanted to visit Elstree aerodrome as a change from Heathrow and Gatwick. Not being too familiar with the location I got off train at wrong stop and had a very long walk to the airfield. I was rather disappointed to find very few aircraft on the field, but I asked a man VERY nicely if there might be any in the hangars?
He took me in a large hangar and it was an absolute wonderland, if I recall about 70 light aircraft and I was allowed to wander about them for ages, I had never been so close to so many aircraft before.
Amother time at Gatwick, using politeness and good manners, I was let onto a Lear Jet and sat in the pilots seat! That was awesome for a 14 year old!
Sad to say in these days of (rightly) enhanced security this is unlikely to be the norm...
