From Associated Press:
Israeli airport police say a couple and their five children were late for a flight to Paris and were in a mad dash for the gate. They remembered their duty-free shopping and their 18 suitcases, but were one child short after take-off.
Late for a flight and "in a mad dash", but they remembered their duty free? 
But wouldn't the passenger count have been wrong? The security implications - from Israel, of all places - are serious.
