Monday morning, arrived at airport - horrendous queues! BAA upgraded security so marquee tents set up outside Heathrow Terminal 4 as "holding pens" (according to check-in lady) for people to wait until they are called for flights. Never seen such a mass of people trying to get, very, very slowly, through the machines. Thank heavens for Fast Track!! (Although even this is more like "Crawl and Snail's Pace Track". Let's hope I don't miss the flight. About to be frisked, so will sign off. Nigel.
