Sounds very similar to the Shag Harbour UFO story:
The Shag Harbour UFO
with the help of
http://www.renaissoft.com/ufocanada/shag.htm The story goes like this:
On the night of October 4, 1967, shortly after 11:00 PM, a UFO some 60 feet in diameter was seen to hover over the water near the tiny fishing village of Shag Harbour, Nova Scotia. The UFO, which displayed four bright lights that flashed in sequence, tilted to a 45-degree angle and descended rapidly towards the water's surface. Upon impact, there was a bright flash and an explosive roar. Concerned witnesses began calling the nearby Barrington Passage RCMP detachment. None of those witnesses mentioned anything about a UFO. Most believed that a large aircraft had ditched into the harbour and that there might be survivors.
Eventually, three RCMP officers arrived at the shore near the impact site. Corporal V. Werbicki and Constable Ron O'Brien, dispatched from the Barrington Passage Detachment, were approaching from east of the site. Constable Ron Pond, who was on highway patrol on Highway #3, was heading towards Shag Harbour from a position west of the impact site, and his position allowed him to view the UFO while it was still in flight. The unusual lighting configuration and flight characteristics tipped Cst. Pond off to the unusual nature of the object long before he heard from Cpl. Werbicki, who received his information through the initial complaints to the detachment.
When all three officers met at the impact site they found that the UFO was still floating on the water about a half-mile from shore. It was glowing a pale yellow and was leaving a trail of dense yellow foam as it drifted in the ebb tide. Neither the Rescue Co-ordination Centre in Halifax nor the nearby NORAD radar facility at Baccaro, Nova Scotia, had any knowledge of missing aircraft, either civilian or military. Cst. Pond reported that the object had "changed" during its descent to the water's surface, i.e., it changed shape, and that it appeared to be "no known object." Later, other local witnesses described much the same details as those of Cst. Pond. Also, a coast guard lifeboat from nearby Clark's Harbour and several local fishing boats were summoned to investigate, but the UFO had submerged before they reached the site. The sulfurous-smelling yellow foam continued to well to the surface from the point where the UFO went down, and a 120 by 300 foot slick developed. Search efforts continued until 3:00 AM and then resumed at first light the next day. Everybody involved was convinced that "something" -- that is, something real and unidentified -- had gone into the water.
The next morning a preliminary report was sent to Canadian Forces Headquarters in Ottawa. After communicating with NORAD, Maritime Command was asked to conduct an underwater search ASAP for the object responsible for the concern in Shag Harbour. Seven navy divers from the HMCS Granby searched throughout the daylight hours until sundown of 08 October 1967. On Monday, 09 October 1967, Maritime Command canceled the search effort claiming "nil results." Outside of the local area, media attention quickly faded.

RAAF Captures Flying Saucer On Ranch in Roswell Region
No Details of Flying Disk Are Revealed

Report Disk Seen
The intelligence office of the 509th Bombardment group at Roswell Army Field announced at noon today, that the field has come into possession of a flying saucer.
According to information released by the department, over authority of Maj. J. A. Marcel, intelligence officer, the disk was recovered on a ranch in the Roswell vicinity, after an unidentified rancher had notified Sheriff Geo. Wilcox, here, that he had found the instrument on his premises.
Major Marcel and a detail from his department went to the ranch and recovered the disk, it was stated.
After the intelligence officer here had inspected the instrument it was flown to higher headquarters.
The intelligence office stated that no details of the saucer's construction or its appearance had been revealed.
Mr. and Mrs. Dan Wilmot apparently were the only persons in Roswell who seen what they thought was a flying disk.
They were sitting on their porch at 105 South Penn. last Wednesday night at about ten o'clock when a large glowing object zoomed out of the sky from the southeast, going in a northwesterly direction at a high rate of speed.
Wilmot called Mrs. Wilmot's attention to it and both ran down into the yard to watch. It was in sight less then a minute, perhaps 40 or 50 seconds, Wilmot estimated.
Wilmot said that it appeared to him to be about 1,500 feet high and going fast. He estimated between 400 and 500 miles per hour.
In appearance it looked oval in shape like two inverted saucers, faced mouth to mouth, or like two old type washbowls placed, together in the same fashion. The entire body glowed as though light were showing through from inside, though not like it would inside, though not like it would be if a light were merely underneath.
From where he stood Wilmot said that the object looked to be about 5 feet in size, and making allowance for the distance it was from town he figured that it must have been 15 to 20 feet in diameter, though this was just a guess.
Wilmot said that he heard no sound but that Mrs. Wilmot said she heard a swishing sound for a very short time.
The object came into view from the southeast and disappeared over the treetops in the general vicinity of six mile hill.
Wilmot, who is one of the most respected and reliable citizens in town, kept the story to himself hoping that someone else would come out and tell about having seen one, but finally today decided that he would go ahead and tell about it. The announcement that the RAAF was in possession of one came only a few minutes after he decided to release the details of what he had seen.
