The cynic in me says that the olympics are just an excuse so that the restrictions can be put in place. They may be relaxed but won't be put back to they way things were.
From my limited dealings with SB on the subject of aviation there is quite a large feeling that they want more control or more information about what private flights are up to. They seem not to bothered about IFR airways flights because there is a record of what you have been up to. But they really don't like the fact that a private flight can fire up and dissappear without anyone knowing where they are going or who and what they have onboard and not talk to anyone.
We even had a very excited SB Sgt turn up with instrument plates they had found on a forgien reg private aircraft wanting to know what they were. He was quite shocked to find out you could download them off the web. He wanted to confiscate my Luchars, Conningsby,Valley,Kinloss, Lossie and Marham plates under the anti terrorism act because they were mil fields and air defense bases. He was quite put out when I said it would be fun in court because the RAF sells them to anyone that phones up with a credit card for 16 quid a set if you phone this number. I might add he did phone the number and wasn't very happy with what the lady at the other end said to him.
