On March 17th 1975 Pat McCarthy of Hamilton Ontario took a series of photos which appear to show a large sombrero shaped craft in-flight. The object was described as metallic and larger than a 747 aircraft in size. As we have not examined the photos first hand we will not offer an opinion as to their authenticity, however what follows is Mr. McCarthy's report and the opinions of those who did analyze the photos during the time period in which they were taken.
On the morning of March 17th Pat McCarthy set out from his home in Hamilton with the purpose of photographing hawks in the nearby Waterdown area. At approximately 1:30pm he decided to pack it in when he noticed something moving out of the corner of his eye. At first he thought it was a frisbee, or a bird, until he realised it was moving far too fast. He attempted to photograph the object, but had great difficulty keeping it in the viewfinder due to it's speed. He was able to get four shots, but it wasn't until development of the film that he learned that he did indeed capture this strange looking object in three separate shots. He continued to watch the object as it straightened out and moved away at a great rate of speed. McCarthy reported that the object diminished in size at a constant rate until it completely disappeared from view.
The camera used was a Praktica Nova 1 (1966), a Hanimar 135-mm lens with a focal length F2-8. The film used was Kodak plus X ASA 125.
The sighting lasted approx. 30 seconds and during that time the object was reported to have displayed amazing aerodynamic manoeuvres. McCarthy reported that at one point it executed a complete figure eight.
