The USAF had a massive exercise out of Lakenheath last week, so not out of the realms of possibility something ducked in flying the
Old Tacan Route over South Wales (stands to be corrected on that one).
Possible long range attack (from USA) and intercept (Lakenheath). Bit worried if they got as far as Newport.
