probably not at the moment, but just after 9/11 I think I got on the UK's watch list for flights. Pre 9/11 I never had an issue at airports.
After 9/11 I was part of a usnet group that chatted about how easy it would be to do the bring a plane down with what could be legally be taken on a plane. Then every time I flew I was pulled out at the baggage scan / fully patted down / a couple of time it was to a booth and take off your jacket, belt, shoes, socks etc / always had to empty my carry-on bag / turn on ly laptop / etc.
This lasted until about 2005 - then just stopped and have never been patted down since
