Catch the train to Cambridge and then bus to Duxford air museum (or you could drive its right by the M1).
Seriously budget a whole day to see the place properly and you MUST go, its epic and you wont be disappointed. I visited the place about three times while living over there. Go to Duxford village afterwards for awesome pub dinner.
Imperial war museum is good, the blitz simulators where you go in underground shelters is well worth queing for, skip the third floor its all holocaust stuff and bit depressing really.
In London find a café near a main route and just giggle and all the lunatics commuting on R1s and fireblades doing stupid stuff lol, engine sounds reverberate nicely off all the stone buildings.
Drive across the Dartford bridge and tunnel and terrify your self on the toll gate approach, prison rules apply to all lane changes, do not brake early....
