A large piece of wreckage from a plane which claimed 13 lives has been moved from the crash site on Bleaklow.
Part of the B29 Super Fortress that ploughed into rocks at Higher Shelf Stones more than 60 years ago, was found 250 yards from the main site.
The mystery has fuelled speculation that it could have been carried away by souvenir hunters hoping to remove it from the moors.
It may have also been moved by thieves aiming to sell it via social media where there is a growing trade for pieces of wrecked military aircraft.
The remains were discovered by a Glossop man who was walking on the moors.
Writing on Facebook, he said he later returned and carried the piece back to the crash site with the rest of the wreckage.
The United States Air Force plane, that was a nicknamed ‘Over Exposed,’ came down in low mist on the hills bordering the Snake Pass in November, 1948.
The entire crew was killed and over the years the crash site has been turned into a memorial to the young airmen.
It is a criminal offence to interfere with the remains or to remove anything from it.
The crash site is legally registered as a monument because people died there and it is given the same kind of protection as a war memorial or cemetery.
The aircraft was flying from Scampton in Lincolnshire to the USAF base at Burtonwood near Warrington to deliver a payroll when it came down.
The crew had completed their tour of duty and in a matter of days were due to return to their families in the United States.
A few years ago descendants of the crew visited the crash site to pay tribute to the men.
Walkers regularly visit the wreckage which can be reached by walking over the moors from Snake Summit.
Wreaths are also regularly laid on the remains of the Super Fortress with a short service on Remembrance Day.
