My son was due to land 20 mins later so was diverted to Stanstead where they refused to let anyone off as not enough staff to cope and couldnt sort customs clearance, so 3 hours on the tarmac and then flew to Gatwick.
Amazingly passport control was quick even though they didnt appreciate his 'oh and Stanstead' comment when they asked where he had flown in from.
He finally got home at 11pm, a mere 18 hours after leaving Calis.
Thankfully everyone was safe.
Far from a crash landing though, a superb landing in the circumstances.
