Bus Spotting? No thanks.

Why not get a train to Cosford (ie, somewhere interesting) or something instead, or even just a local GA field?
"Bus spotting" and Heathrow may just be interesting to some people Steven.. each to their own ;)
My delight is getting on my Motor Bike and popping up to my local Airfield, (EGBS), whenever there is a General Aviation fly-in, or Air Race, or a Barbecue, on the menu....

ASL AGL...(and out of sight/sound)....
