for those who are fluent in real UFOLOGY , they know by heart the BOAC stratocruiser sighting UFO case
for those who are new to UFOLOGY you can read the full statement and investigative document here
The summary of the encounter is quoted below :
This observation was made by crew and passengers of a 4-engine Boeing Stratocruiser of the British Overseas Airways Corporation. Flight 510-196 was a
luxury flight bound for London departing New York at 17:03 local on June 29, 1954 with 51 passengers aboard. Four hours later at sunset, 19,000 ft
(5,791 m) over Labrador, Newfoundland, and en route for Goose Bay, an apparently huge shape-changing UAP  and a swarm of small attendant objects
was seen against the bright sky off the left wing. The strange display persisted for 18 minutes.
Whats so strange about this sighting is the event leading to it, as stated by the pilot. He said he was asked by the flight control to delay his
OUTBOUND flight. He said its strange to have a delay on the outbound leg since usually its the inbound leg that was delayed.. read quote below :
A final note concerns Capt. HOWARD's recollection (1967; 1982) that soon after departing New York the Centaurus was kept in an unusual - indeed,
unique in his experience - 10-minute holding pattern by Boston ATC before being allowed to proceed to Goose by way of a diversion to the East of
Boston. No explanation was given.
as a side note, there is unconfirmed 3rd party witness that may have connection to the reason of that delay :
after the sighting Capt. HOWARD received a letter from an American doctor who had been holidaying in a Massachussetts lakeside cabin on that evening.
They had heard a "roaring" noise and looked up to see seven dark objects - one large and six small - heading NE across the lake. Capt. HOWARD
wondered if these might be the same seven "strange things" he had seen, and if so, whether they were responsible for Boston ATC radar re-routing his
aircraft away from the area.
Assuming that the delay have any connection with the later BOAC sighting, did flight controllers know something or being ordered by someone
(military/intel) to prevent civilian aircraft moving into certain areas that have anomaly detected ? i understand military and civilian got different
air corridors and everyone stay on their respective pathways, unles its an emergency.. but a 10 minutes no explanation wait time is a bit strange in
this case, given the following incident with the phenomena.
