This August 1949 technical report from the US Air Force Air Materiel Command presents Project Grudge's investigation of unidentified flying objects through January 1949. Drawing on consultants including Dr. J. A. Hynek, Rand Corporation, the Air Weather Service and Dr. P. M. Fitts, it explains most of 244 incidents as balloons, aircraft, astronomical phenomena, hoaxes or psychological errors. It concludes the objects pose no direct threat to national security and recommends reducing the investigation in scope.

If the object itself was, it would not have been a shoer, but the glist of the repeat series to indicate that only the trail was visible for any length of time. In that case, it could have been either the trail from a retour of the water trail from an aircraft, the description is not sufficient to dictate quite the two. Vener observers (not those in airlift) indicated that the object was a high flying plane with a water trail, but this does not necessarily exclude the potential hydro-turbals, seawater or the general unavailability of the surface with ocean phenomena.
