Sorry, I'm sure I'm missing something here...
Can anyone please tell me, what is going to (or what could) happen at the Olympic games that requires this restriction placed on the airspace for 20/30 miles around it in every direction?
Analogy: Do they restrict the airspace above a football stadium during a big game? No...
Very confused by this! I'd be tempted to turn the Xponder off and fly lowish...!
