There comes a time when only flying at night to maintain secrecy doesn't give you the best capability. Keeping a weapons system secret costs a disproportionate amount of $$. The facilities that the F117 Force used are now discussed openly on the internet. F117 was an amazing platform and the UK was privileged to have been involved. ..............But even F117 pilots needed a life. We could never have achieved the same programme in UK; the guys who ran it have my entire admiration.
