A Youtube video shows how anyone can open the toilet door on a plane from the outside.
Youtube Sándor Tarnóczi explained how someone can find the hidden way to open the door.
A latch is seen to be concealed underneath the lavatory sign in the video, which with a simple flick, opens the door.
The reason for the feature is for safety, however, for flight attendants to get in in an emergency if someone is taken ill or a child gets stuck.
YouTube users were notably impressed, with one commenting: “This is the best thing I’ve learnt since school.”
Yet for anyone thinking they still want to join the Mile High Club, they should check the airline and where they are flying to.
Many destinations and airlines deem it illegal to do and could receive huge fines.
Virgin, however, have said to be open for those wanting to try it out for themselves, with Richard Branson confirming that flight attendants are “not to bang on lavatory doors when a couple slips in there.”
It’s not the only secret to emerge from the aviation industry.
Pilots recently revealed some of their biggest secrets and what they never want passengers to know.
From not telling passengers the plane has been hit by lightning, to a gun being in the cockpit, some of the facts revealed are quite frightening.
Yet they are mainly done to avoid any passenger panic whilst in the air.
