Mirage was indeed burgled from the Fairey Delta 2! Peter Twiss captured the world record at 1132 mph; the aircraft was later fitted with an 'ogival' wing and took part in the Concorde programme as a high-speed research aircraft. Its stablemate, the HP 115 took car of low-speed research (and Dutch rolled like crazy!).
Tu-95 Bear was developed from the Tu2 'Bull' - itself a copy of the B29 Superfortress.
VC10 has a majestic appearance rather than the marked anhedral of the Il62 'Classic'. The reason being that anhedral makes the ac less liable to Dutch roll (ask your QFI) and the '62 has spring tab 'manual' ailerons (and a HUGE control column!).
I hope that there's no truth in the rumour that the Iraqi Fury ISS has been vandalised by the ignorant dung-eaters. The same people who vandalised the airport - including defecating in the baths....or so I'm reliably informed.
