QuestionsIncident 88: the Hackensack disc, 3 August 1947What did the three witnesses see over Hackensack on the evening of 3 August 1947?Answer
Answer · Incident 88: the Hackensack disc, 3 August 1947
A small balloon carried on the evening's light south-westerly wind
The object was a small balloon, such as a child's or party balloon, drifting on the light south-westerly wind and lit by the low evening sun.
Where it stands
Still possibleOne piece of evidence for, none against. It needs two reviews to be accepted.
What it predicts
- Upper-air winds near 200 m that evening blew toward the north or north-east.
- A balloon of about 0.3 m at 50-80 m matches the reported angular size and makes the reported angular speed.
- No other observer farther along the course reported a disc.
What would rule it out
- The wind near 200 m was from the north or east, so a balloon could not have moved north.
- A reliable record shows the object rising against the wind, hovering or turning.
