Quick facts

What was the British Flying Saucer Working Party?
The D.S.I./J.T.I.C. Working Party was a joint UK scientific intelligence body convened to evaluate 'flying saucer' reports. Its June 1951 Report No. 7 (DEFE 44/119, Copy No. 17, classified SECRET/DISCREET) reviewed the 1946 Scandinavian ghost rockets, Kenneth Arnold's June 1947 sighting, U.S. Projects Sign and Grudge, and three 1950 UK incidents reported by RAF officers.
What did the Working Party conclude?
DEFE 44/119 recommended the MoD undertake no further formal UFO investigation absent material evidence. The Working Party assessed the available reports did not establish any object of non-conventional origin. Its conclusion influenced MoD policy through the 1950s, later revisited when Project Condign was commissioned in the 1990s.
How does this document connect to later UK UFO policy?
DEFE 44/119 is referenced in Project Condign Volume 1 (December 2000) as a precursor to the MoD's formal UAP analytical approach. The Working Party's 1951 recommendation against investigation became the baseline MoD posture that Condign was eventually commissioned to reassess.
