Edgar Brooks
Senior Airman
We know that now, 70 years on, but the Air Ministry didn't in 1944/5, hence the desire for secrecy.[The knowledge about metallurgy in Germany was at least equal to the knowledge in Britain.
The Air Ministry didn't make a statement; it's included in inter-department correspondence, in classified files, which were only opened to view around 1975.IMO the statement of the Air Ministry was only for propaganda reason.
