Went to London with Sarah today to window shop in Knightsbridge and the Kings Road. Felt underdressed in various locations. Sarah scandalously violated the window-shopping ethic by buying something.
Didn’t see any of the supposed additional security measures: we certainly didn’t get our bags searched on the train. There were, however, lots of airport-style tannoy announcements telling us not to leave bags unattended. I’m sure it gives someone the warm and fuzzies.
I did catch a brief glimpse of what I’m sure was a passenger jet being escorted by two fighter jets. The louder-than-usual jet noise alerted me, and I looked up just in time to spot them – fighters tickling the wing tips of the passenger jet – before they disappeared behind a building. They were banking right, not following the usual Heathrow approach (at least compared to the other aircraft we saw). I had my camera with me, but no time to take any photos.
Haven’t seen anything about this on the web. Maybe it’s so common these days that it doesn’t register as newsworthy any longer.

Escorted jet
Twas 2 tornados and a nimrod.
The flypast took place at 12:55 hrs to mark a service at Westminster Abbey.
Re: Escorted jet
Ah, that explains it. I guess the silhouette of a Nimrod isn’t that much different from the silhouette of a passenger jet when you only see it for half a second.
