BUT the judgement of the height of aircraft height and speed is difficult, especially an unfamiliar a/c against a backdrop of grey sky.

70. Mr Holbrook explained to us that he had repeatedly but unsuccessfully asked to see photographs of a Chinook at different heights and ranges, in order the better to estimate the height and speed of the aircraft when he saw it. He clearly felt that he would have been in a better position to assist the Board had he been furnished with such information. We do not know why the Board did not accede to his request or afford him the opportunity of seeing a Chinook in flight.
