I still prefer the crane with a large piece of bungy attached engine noise and spinning prop a problem already overcome. I am am sure Baz with his skill on photo shop could give us and artists impresion ?. 10% off for you Robert!!:diablo:

Hang on just a minute.

A number of years ago I wrote an article in FlyPast on this EXACT principle, based on papers belonging to my late father, who worked for the civil engineers, Rendal Palmer and Tritton. It was on the subject of concentric launchers, by which the aeroplane ( Spitfire in the artist’s impression ) was whirled round a pylon until it attained flying speed.

It was proposed at a time when the country was awash with nutty ‘war-winning’ schemes- fortunately it was never built.

The article was published in the early 90’s, and the cover of the mag had the silver MATS Constellation (on ground ) against a lot of blue sky. I would find my copy but it is in deep storage.
