high-altitude pulsed contrail
Saw the thin, single-strand contrail (approximately four inches at arms length) of a rapidly-moving high-flying object in a cloudless, clear-blue afternoon sky. The contrail, formed by unevenly-spaced pulses, quickly dissipated. Could not see the eastbound aircraft itself with the naked eye. Estimate that it was flying higher than crosscountry jetliners, which appear to move slowly across the sky at cruising altitude. Initially saw the contrail of this object as it moved directly overhead. It disappeared in the distance with amazing speed. Viewing location was somewhat noisy so cannot report any sounds.
