A couple that I've enjoyed recently, though they may not suit the OP's brief:
Empire of the Clouds: When Britains Aircraft Ruled the World, James Hamilton-Paterson. A readable and interesting account of the British aircraft industry post WWII.
Vulcan 607, Rowland White. The raid on Stanley, one of the most outrageous bombing missions of all time surely, and one of my favourite quotes:
"air-to-air refuelling is like pushing wet spaghetti up a cat's arse".
Long distance touring, not much comfort.
Finally, my current bed time book is The Spirit of St Louis, Charles Lindberg. A fascinating read, surely the ultimte tale of human endurance and pioneering spirit. Moreso even than the Mercury Astronauts IMHO.
