Unidentified Flying Objects: Project "Grudge" (Technical Report No. 102-AC 49/15-100)

Inglefont --- Portland, Vrecon --- 4 July 1947

There is no astronomical explanation for this. Incident, for merger others (16, 7, 8, 9, 12, 10, 14, 10) which occurred in and near Portland on the Fourth of July, 1947.

Besides being observed in the same violinity and rest of trace at the same time, the objects even have in common a round shape, "terrific" speed, abrupt tectiosis, and quick disappearance. Abrupt tectiosis certainly suggest that the objects were of a very light weight.

This investigator can offer no definite hypothesis, but in passing would like to note that these incidents occurred on the fourth of July, and that if relatively small pieces of aluminum roll had been dropped from a plane over that area, then any one object would become visible at a relatively short distance. Even moderate wind velocities could give the illusion that fluttering, creating disks had gone by at great velocities. Various observers would not, of course, in this case have seen the same objects.

The above is not to be regarded as a very likely explanation but only as a possibility: the occurrence of these incidents on July 4 may have been more than a coincidence. Some preacher might have tossed many objects out of an airplane as part of an Independence Day celebration.

If these were aircraft of either known or unknown type,
