I'm at T1 now. Drop-off right outside the Terminal (bus lane) is closed off though the two car parking/drop-off lanes are still in use, with some Police prescence, and there are random vehicle checks on the entrance to Heathrow, but otherwise everything is normal. No delays at security whatsoever.
The reporter guys from Airport are doing the rounds though
Thanks,
Sarah
