ⓘWhat do the D1–D5 confidence tiers mean?›
- D1A single attributed public source (museum, council, Historic England, CWGC, mapping data).
- D2Two or more independent public sources corroborate the same facts.
- D3A named coordinator or local reviewer has confirmed the public-source account.
- D4A named observer has personally visited and documented the site — photographs, inscriptions, condition.
- D5An archive or institution has provided written documentation supporting the entry.
A higher tier means more corroborating evidence, not automatic historical certainty. The Discovery layer does not replace archival verification.
In the surviving control tower of the wartime airfield at Thorpe Abbotts in Norfolk, a memorial and museum honour the 100th Bombardment Group of the United States Eighth Air Force — the "Bloody Hundredth" — which flew B-17 Flying Fortresses from here over occupied Europe from 1943 to 1945 and suffered heavy losses. The memorial records the group and its squadrons.
