Hamilton Ontario: Large Disc Descends and Fully Submerges in Lake, Five Adult Witnesses
In late August 1981, during the afternoon, five adult witnesses observed a large disc-shaped craft maneuvering through a mountainous area east of Hamilton, Ontario, south of Lake Ontario. The object — estimated at more than three to four car-lengths in diameter — approached the group at moderate speed, passed directly in front of them at low altitude, descended smoothly to the water's surface in a nearby bay, and then fully submerged without producing any splash or disturbance on the surface.
The witnesses observed the entire sequence from approach through submersion, which lasted several minutes. No sound was reported during any phase of the encounter. The case is cited in the AAWSAP configuration study as a documented example of transmedium capability — the ability of an object to transition seamlessly between atmospheric flight and underwater operation. The multi-witness nature and the daylight conditions under which the observation occurred strengthen the case's evidentiary value.
Background
In 1981, five adult witnesses in Hamilton, Ontario, Canada observed a large disc-shaped object descend from the sky and completely submerge into a lake.
The craft was described as metallic and substantial in size, performing a controlled descent into the water.
The Incident
Five adult witnesses saw a large disc-shaped object descend and fully submerge in a lake.
The event occurred in 1981 in Hamilton, Ontario, Canada.
Witness Descriptions
- Witnesses: five adults
- Object: large disc-shaped, metallic, substantial in size
- Behavior: controlled descent from sky into water, fully submerged
Significance
This case is significant as an early documented transmedium event.
Transmedium refers to a UAP transitioning between aerial and aquatic environments.
Witnessed by multiple credible adults.
