We had an Aerovan at Burnaston that was with a photo survey outfit. I worked on it a little and seeing the waves on the top of the wing was something to behold!
The pilot was a lady ( Jean ??) and the camera operator was Chris ??? . I am sure HP will fill in the gaps!
They were both killed when one of the props came off ( Cirrus crankshaft sheared) and went through the fuse.
