For those interested in engineering I now have available a seven page mathematical analysis of aerodynamic loads likely to be experienced on a BobCat elevator at 200 fps in an air density of 0.002378 slugs/ cu. foot. This was written independently by a retired aerodynamicist who worked on the Concorde project and latterly on satellite design ( he is also a structures expert).

As my honest and genuine attempts to contribute towards finding an answer to this elevator problem have met with hostility in some quarters, the question is what should I do with this paper, the maths . of which go way over my head ?

Mr Faulks who wrote the paper has come up with much the same answer as reached by Bob Parks in his initial assesment of the loads.
