The SPEERESAND PLANE

Report on the vision of a ring shaped flying plane seen in the sky,
by the author, about the end of October or the beginning of November,
1951, over the City of Montreal, at the intersection of Decary Boulevard
and Sherbrooke Street.

Part I

On a clear night, at about 11 p.m., the author was standing on the northwest side of
Decary Boulevard and Sherbrooke Street, gazing up the hill and waiting for a bus to
go downtown; but...no bus...as usual.
At the intersection of Notre Dame de Grace and the Boulevard, 1980 feet away from
Sherbrooke Str…

The SPHEREANNO Plane Part I Page 2

At the very line of vision of the vanishing point of the first ship, a work point was instinctively located on the roof of an appartements block, across the Decary Boulevard, south of Sherbrooke street, and upon inspection was earmarked as of being approximately 100 feet from the north corner of the appartements block.

The observation proved to the author, without a single hint of mistake, that the disc-ship seen was a "SPHEREANNO" plane as never seen or heard of previously, except as referred to as "floating inland", supposed to be designed by…

The Triangulation of the Observation. Part III UNCLASSIFI. Pmd 5 AF-473351

The triangulation would have been almost impossible without some basis on which to stand for figuring the size, the altitude and the speed of the sphereanno plane. Three guesses were made and two lucky markpoints plus the timing were fortunately available.

First guess: - The near edge of the plane appeared and was guessed as being about at the zenith of the observer's position (0);

Second guess: - The speed of the ship appeared and was guessed as being about equal to one diameter of the sphereann…

The SPHERMANNO Plane Part III Page 2

From these assumptions the altitude of the plane is easily determined by the triangulation data of drawing 2, thus:-
$$ \frac{48}{35} = \frac{x}{1082.62} \quad \text{so} \quad x = \frac{43 \times 1082.62}{35} = 1350.8 $$ or 1330 feet = Plane's altitude.

The final stage of triangulation involves the angle of vision at the very moment of the disappearance of the sphereanno plane for which there is fine markup in as shown on drawing 2 figs. 1 & 2 at points (0, 4), and as shown below:

The angle at wall edge of court as per markpoint (4-a) t…
