At the temple of King Seti I is a hieroglyph created some 3000 years ago which looks like a helicopter complete with rotor blade, rotor shaft, tail-piece, cockpit and fuselage sections clearly visible. Underneath is an image resembling an aircraft or submarine with a fin at one end. Did the ancient Egyptians understand the principles of flight and did they possess the engineering expertise to build helicopters and airplanes?
