The flight was supposed to take of from Manchester, U.K. and head to Pakistan when the incident occured. Even though the passenger made the mistake while the plane was still grounded, it lead to a seven hour delay! They were actually able to open the emergency exit so it caused the exit slide to deploy automatically, causing all 40 passengers to need to deplane. I don't fly often, but every plane that I have been on I was able to easily tell the difference between the bathrooms and the emergency exits so I was amazed to read this has actually happened several times and some recently. Maybe planes from other countries are different? Click the link in the tweet below to read more!
