Sir P
I for one am extremely grateful for that day in the toy shop when it was decided to buy the biggest, shiniest and most expensive model on the shelf. I have had so much fun with those fiddlley complicated bits, in fact so much so that I never noticed how smeary the windscreen had become, but then at night who cares?
Now who told you about the glue thing? I've always got by with duck tape.
Just a point, there seems to be a lot of engineers posting geeky stuff here, can't they go away so us Aircrew types can do what we do best..........
