1 The botulism neurotoxin is one of the most potent, lethal substances known.  Botulism is a disease caused by this neurotoxin (specifically A, B, E, or F type neurotoxin); symptoms include a flaccid paralysis (weakness or slackness) in various muscles.
On that trip I used both Gatwick and Heathrow airports, as I stayed in London a few days then went on to Madeira, Portugal via Gatwick. When I first arrived from the US, I came into London Gatwick around 8am. The line for customs was miles long and it took about 30 minutes to get through.But when I came into Gatwick around 5pm from Madeira it was a ghost town. I kid you not, there wasn't a soul in the line, and the baggage re-claim area was dead quiet.ast Tuesday, it took 45 minutes to get to an immigration officer through a queue line that would do Disneyland proud...the immigration inspection took oh about 15 seconds, she looked at my landing card, my passport, asked how long I would be in the UK, stamped my passport and said, off you go..
The recommended arrival time at the airport is 75 minutes prior to departure when traveling within the United States. You must be checked in at least 30 minutes before your scheduled departure time.
