SUBJECT: Unidentified Aerial Phenomenon

TO: TDEW

1. Reference: Sighting of 18 April 1964 1930L near Manassas, Virginia. The time, location and description suggest this sighting may have been the 19 April 0030Z radiosonde release from Washington, D.C.

2. Supporting facts

a. The radiosonde train consists of a balloon, a radiosonde package and another intermediate object. Oscillations of the radiosonde pac…

(e.g., 270 degrees is a wind from the west, 250 degrees is from south of west). The rise rate is 1000 feet per minute. The 250 degree winds would carry the radiosonde train into the NE quadrant which would appear to the observer as a movement to the north. The apparent motion would be more noticeable than that caused by the higher winds which occurred at higher elevations and from the NW quadrant. At this later time the distance of the radiosonde from the observer reduces the apparent motion.

3. No explanations of this nature are conclusive but there is enough consistency between Mr. [redacte…

Dear Mr. [redacted].

This letter is in further reference to the sighting of an Unidentified Flying Object you reported seeing on April 18, 1964.

The time, location and description of this sighting coincide with the release of a radiosonde balloon in the Washington, D.C. area.

The radiosonde train consists of a balloon, a radiosonde package and another intermediate object. Oscillations of the radiosonde package may cause the entire train to take a triangular shape from time to time. The release time of the radiosonde train preceded the sighting sufficiently to allow a climb to …
