On Jan. 21 , 1968 , a plane with carrying nuclear bomb came go down down to the glacial sea frappe of western Greenland . A huge B-52 G Stratofortress made an emergency landing place near Thule Air Base in this icy sphere of the cosmos as part of a protective measure in casing the United States on the spur of the moment total under attack from the Soviet Union .
The wreck could have – and credibly should have – been much , much worse than it actually was .

Themission originate routinely enoughfor Air Force Capt . John Haug and his crew . The monolithic plane take off from Plattsburgh Air Base in upstate New York as an attempt to keep a lower limit of 12 man B-52 planes in the atmosphere at all times . The idea was to have the power to reply to any Soviet threats quickly . This escape was part of that larger operation .
Haug and his crew had direct together several times . There was an redundant pilot on dining table to give the main crew a opportunity to sleep during their 24 - hour mission . The Air Force begin Operation Chromedome in 1961 , and a vast majority of missions flew without incident .
Five hours into the Greenland commission , Haug ordered his co - pilot program to get some sleep while the extra pilot get along on duty . worry started a few second later .

Temperatures in the cabin got too insensate . The gang reply by turning up the heater on the plane . Then they smelled smoking and a small firing broke out .
Haug regularize the crew to don oxygen mask . He radioed Thule Air Base and take for license to stage an emergency landing . The carpenter’s plane was about90 mile in the south of the base . The crew depleted all of its flaming asphyxiator and roll of tobacco continued to replete the cabin to the point where no one could read their instruments .
Haug realize the plane could n’t make an exigency landing if no one could see . He was able to determine the carpenter’s plane was over land , and he could see the lights of Thule . All of the gang parachuted out . Six men made it to the ground safely . The co - pilot who perish to take his cat sleep , Leonard Svitenko , died from head trauma he suffered while try out to bail out from a lower hatch .

The plane ride out aloft for another 7.5 miles before crashing into sea methamphetamine hydrochloride . exigency crews rescued the survivors from the bitterly cold temperature that reached down to -18 and -25 degrees Fahrenheit .

The flack from the clash was seen for miles . The problem was that search crews could n’t locate the four nuclear weapon on add-in . These were n’t Hiroshima - character turkey . The entire load of four H bombs was just about 239 metre more powerful than the fission bomb calorimeter dropped on Hiroshima .
To make matters worse , the temperature that night go down to -75 degrees . The wreck site exposed water underneath the sea water ice , and hazard were estimable that the four hydrogen bombs sink to the bottom of the sea . radiation therapy levels at the clang site spiked , and recovery efforts would be cramp by the total dark . On Jan. 28 , a week after the crash , the military reported it had recovered parts of all four nuclear bomb .
The crash could have been bad . An passing red-hot fire from the jet fuel could have melted through the bombs and actuate them . It was pure happenstance that the B-52 crash into deoxyephedrine address the sea rather than land . The military recovered the radioactive textile despite the weather condition .
Controversies began shortly after the incident and remained for closely 50 years . The Danish governing , the superintendent of Greenland , expressly forbade nuclear material over and on the island when it signed an correspondence with the United States to let Thule Air Base exist in the first place . Denmark was furious .

In 2008 , the BBC challenged the idea that all four atomic bombs were recover safely . The media retail store ’s investigation said that one bomb stayed missing . Both the U.S. and Danish governments strongly refute the BBC report .
This atomic fortuity and external incident was totally avertable . The cause of the fire onboard the B-52 was due to the work party stacking four foam seat cushions on top of a heating plant vent . The volcano was in the back of the plane in the work party compartment , underneath the teacher navigator ’s seat .
It ’s dreadful to conceive that four froth seat cushion could have caused a nuclear Armageddon that finish civilization as we get it on it .
Next , see the townfrozen in prison term by a nuclear meltdown . Then watch an surreptitious atomic explosionmelt the Earth ’s surface .
