Back when I was a kid in the smallish UK city of Lincoln, we had two big model shops (tools, balsa kits, aero engines, Airfix, etc.), one big toyshop (Scalextric, and toys for young kids) and one rather weird place that specialised in fishing gear, Meccano and 00-guage railway stuff.

Now all are gone, and I do wonder how kids of today will be able (for e.g.) to experience building a glider (balsa, cutting out with a razor, tissue covering with paste) and launching the final product into the sky. We have lost something.

BTW, if any of you or your children want to get into things aeronautical I can strongly recommend https://www.amazon.co.uk/Penguin-Book-Kites-. Some string, a little bamboo or dowel, and a binbag and you are ready to go.
