“BRIEF SUMMARY OF SIGHTING:

Shiny-metal color. Circular shaped. Seemed to close on B-36 then made sharp turns. Might have been fighters however description precludes this. Too bad altitude of B-36 is unknown.

COMMENTS:

Overtook B-36 at 3x B-36 speed. Hovered near B-36 then disappeared by getting smaller.”
