Secrecy surrounds the English Electric Canberra's past but the aircraft was likely used for reconnaissance missions, peering over the Iron Curtain, helping to find mass graves in Kosovo and spotting IRA weapon dumps in Londonderry.
It has gone on the market for £70,000, a snip compared to the £850,000 - the equivalent of £18m today - it would have cost to make in 1959.
With a whopping 65ft wingspan and standing nearly 15ft tall the two seater jet would dwarf the average garage.
The Canberra has the ability to fly at 70,000ft and travel at an eye-watering speed of 540mph.
These capabilities allowed it to outrun the piston-powered fighters of the 1950s and was the RAF's first jet-powered nuclear bomber but its role was adapted as the Cold War developed. Bomber Command retired the last of its Canberras in 1961 and they were fitted with cameras to spy on targets deep inside Eastern Europe.
This aptitude for surveillance saw the planes used in every major British conflict until they were retired in 2006 and replaced by drone technology.
This two-seater aircraft for sale, known as XH134, served on tours with the RAF 13 Squadron, 39 (1 PRU) Squadron and 58 Squadron.
By the time it was retired it had accrued a staggering 9,300 hours - 387 days - of flying time. It was bought from the RAF by the display team the Midair Squadron and flown at air shows alongside the Red Arrows and iconic Vulcan Bomber.
But the private company went into administration last year and the aircraft is now being sold by London auctioneers Bonhams. Rob Hubbard, of Bonhams, said: "This is a tremendous a piece of British aviation history, you certainly wont find another one in this country.
"The problem is one hour of flight is going to cost you £50,000 so the initial price is a drop in the ocean compared to running it.
"It is one hell of a big boys toy though.
"Anyone can buy it, it is moving it that is the difficult thing as it is so big. It can be used for flying or put it in a hanger as a museum piece or maybe used for marketing.
"This is the only Canberra aircraft left flying and was retired from its military service in 2006 when the RAF phased them out of service.
