This is the moment a man unveiled his home-made plane in front of crowds and television crews - only for it to crash down seconds after take off. Gabriel Nderitu, from Othaya, in central Kenya, assembled the aircraft himself and was making a sixth attempt to get it off the ground. The 48-year-old's invention set off and roared up a specially-made wooden ramp - only to nosedive seconds later just metres after take-off.
