Incident /73 -- Boston, Massaohusetts --.4 August 1947
There is nothing in the evidenee given here to su gest
that the object sighted was astronorical.
The deseription suggests rather tnat the objoct may
have been a highly distorted roflection imnge of the sun on a
balloon or aireraft. The "deep gold" color ascribed to the object
tonds to indicate this interpretation.
