This would have been awsome on April Fool's!!!
About 275 passengers on a Tuesday flight out of London's Heathrow Airport heard the message: "This is an emergency. We may shortly need to make an emergency landing on water," NBC News reported.
"People were terrified, we all thought we were going to die," passenger Michelle Lord, 32, told Britain's The Sun newspaper, which first reported the incident. "They said the pilot hit the wrong button because they were so close together."
