01 / DOCUMENTED CORE
Start with what the record can carry.
On 21 January 1968 a U.S. B-52 carrying nuclear weapons crashed near Thule Air Base in Greenland.
The crash, conventional detonation of weapon explosives, radioactive contamination and cleanup are documented. The archive separates those facts from stronger claims about hidden weapons or missing components that require claim-level evidence.
02 / CASE RECORD
What is established.
The aircraft carried nuclear weapons.
Conventional explosives detonated and radioactive debris was dispersed; there was no nuclear detonation.
The accident triggered cleanup and U.S.–Danish diplomatic consequences.
03 / VISUAL RECORD
Images with a declared evidentiary role.
Actual 1968 crash-site aerial photograph.
04 / CLAIM LEDGER
One claim at a time.
CLAIM 01A nuclear-armed B-52 crashed near Thule in 1968.
DOCUMENTEDThe status applies only to this claim. It does not automatically transfer to other allegations in the file.

05 / TIMELINE
The sequence matters.
