Soundtrack
The lack of a correct soundtrack is quite possibly because the MD 902 is probably the quietest chopper flying and they (the producers) are trying to enhance the film drama. I live under the approach to Gloucestershire Airport where many 902s go for maintenance and never hear them. I only know if one is passing over if I happen to be outside at the time. Always hear 135s, 105s, 109s and all the other popular makes.
