I'd hazard a guess that most kids would love it it. As for the elderly - here's one old codger who wished we had some of this around here - all we get is boring old Merlins!
Here is another old codger who wishes there was more around. My first apartment in Germany I was right under one of the low flying routes for the Luftwaffe Eurofighter, choppers, etc. It was superb when i was at home to sit on the balcony and watch them fly down the valley. Slowly the number of Eurofighters diminished (see another thread for the reasons). In my last year in that apartment I did nor see one. Now i live in the town and the only flying things are leaves in the autumn, ducks an the odd police chopper.
