Millions of people fell for an elaborate April Fool's Day hoax featuring video footage of the world's first flying hotel in a converted helicopter.
The viral email clip appears to show a Russian-made Mil V-12 being used as the first-ever flying five star 'Hotelicopter'.
It was said to have 18 luxurious rooms "for adrenalin junkies seeking a truly unique and memorable travel experience".
The clip became an overnight internet sensation but it later emerged the video, on www.hotelicopter.com
