The following questionnaire was a key component in the U.S. Air Force's investigation, under the auspices of Project Blue Book, of more than 12,000 UFO sightings between 1947 and 1969.

The following is a rough transcription of the notorious questionnaire as UFO witnesses would have received it in the mid-1950s. Other than a few typographic changes to make the document read more smoothly in the online medium, it has been left in its original form.

If you have a sighting of your own to report, feel free to complete the survey. But remember: The Air Force no longer actively investigates UFO reports since Project Blue Book was terminated in 1969. Likewise, NASA has other things to think about, so they won't be too helpful.

Please note that we do not actually need your address or telephone number; only a return e-mail address is necessary for contact purposes.
