Seems as though sleep-deprived passengers on long night flights may be getting their own back on noisy crews and the noise of engines and air-conditioning.
I just read a report that air crew flying the Airbus A 380 ‘super jumbo’ have been disturbed by passenger noise when resting due to the extremely low noise level of the aircraft. A spokesman for Emirates, whose staff complained of the disturbance, said that they would play engine noise to the crew to simulate the noise of a normal plane!
How about marketing engine-noise CDs to help jet-lagged passengers come down to earth?
