My BA flight security leaving the US into Heathrow was extremely heavy. Just before boarding, they pulled many passengers aside to check with wands, remove shoes (again), search carry-on luggage, etc. I can only imagine the security checks on BA 223. Best wishes to them. I have said a prayer for them.
