I hate to spoil a good story, especially a skeptical one, but is there something slightly adrift with William Ireland’s piece on the Kaikoura UFOs?
He says the camera was looking down at an angle of perhaps 38 degrees, but does not use the figure to explain anything. However, looking down at that angle, at an object 6 km away, implies a height of 4.7 km, or 3.7 km if the distance is measured along the line of sight. But I thought an Argosy typically flew at about 6000 or 8000 feet, or 1.8 – 2.4 km.
The 6 km is given as a minimum, so the discrepancy could be worse than this: if the distance comes from the aircraft radar it should be reasonably reliable, so does this mean the angle is wrong, or my figure for a low-tech aircraft cruising height, or what?
