There is a book that I am sure that you will have read, but just in case, it is entitled Project Cancelled by Dereck Wood, published by Janes, ISBN Number0 7106 0441 6. Pages 18 to 24 cover the Miles episode . My own view having worked on various projects concerning supersonic flight that the then government was indeed bankrupt ,and were prepared to give in return for goods, favours or even hard cash, any kind of research or developement that had been undertaken. Another example is the sale of 18 RR Derwent jet engines which went on to power the Mig 15 prototypes. Hope this helps Alan
