|High speed UAP sound in 2.5 seconds.
Bright sunshine, occasional cumulus clouds. Sitting under covered porch reading. Heard a startling abrupt sound of a low altitude missile-like object directly overhead and it quickly sped south. In the three porch steps it took to get a clear view it was gone. 2.5 seconds duration. No vapor trail. I have seen many high-speed low altitude flyovers of military jets, and I learned that the sound is not detected until the plane is overhead. This sound matches that characteristic except for a major difference. This object had a thin faint sound. The sound was like air rushing over a cylinder or fuselage. There were no engine sounds, no thundering afterburners, no loud rushing sound of a military jet. No doppler change. It was gone in about 2.5 seconds.
Never heard such a unique aerial sound as that before. My perception is its speed was hypersonic minus sonic booms. I have no air tank systems, no liquified gas tanks (venting).
