Summary

The incident was reported for the evening of 4 October 1955, when Senator Richard B. Russell's party was travelling by train from Baku to Tiflis. A US Air Attaché report said two sightings occurred at 1910 hours, ten minutes by rail after leaving Alyaty. The Air Attaché in Prague, Lt. Col. Thomas S. Ryan, debriefed Lt. Col. Hathaway and Mr. Efron on 13 October. He wrote that the interview lasted no more than one hour and that Senator Russell did not attend. Ryan's cable and report described two disc-shaped craft ascending almost vertically to about 6000 feet. His comment said the report's significance to the USAF project was "remarkable and lends credence to many 'saucer' reports".

CIA officers interviewed Russell on 27 October. Herbert Scoville Jr.'s memorandum recorded that Russell saw a greenish-yellow ball rising rapidly and never saw its form. Scoville wrote that it was quite possible the objects were exhausts of normal jet aircraft in a steep climb, or aircraft with short or near-vertical take-off. A separate CIA record of Dr. Francis Clauser's interview had Russell describing a steep, non-vertical trajectory and a searchlight that did not follow the objects. It also said the train guard or porter drew the shades at least 10 minutes later.

A CIA memorandum of 31 October, addressed to the Director of Central Intelligence, summarised all four witnesses. It recorded that Efron saw two lights, Hathaway a shadowy object with a rotating light, and Gros a triangular object with three lights. It stated that only Hathaway's testimony would support a radically unconventional aircraft. It concluded that the other observations could probably be explained as steep climbing aircraft or missiles. The FBI's 4 November memorandum repeated this summary.

A separate CIA information report of 15 November carried the account of a 41-year-old US civilian, labelled unevaluated information. He described an equilateral triangle on an airfield, ejected with spirals before climbing at about 45 degrees. He said the steward pulled down the blinds after an MVD man ordered it.
