10. BRIEF SUMMARY OF SIGHTING Aircraft of unidentified type observed by American Air Lines pilot flying 20,000 feet over the Sange de Cristo range. There were no vapor trails or other distinguishing characteristics observed which might assist in the positive identification of this particular a/c type.

11. COMMENTS Immediate identification of object observed by commercial pilot as being a type of unrecognized a/c precludes investigation on basis of sighting being a UFO due to scattered cloud conditions at altitudes & limited visibility it is highly possible that under better conditions this experienced pilot could have better determined the exact type a/c, No Inves.
