Report COM-2021-266

A Boeing 737 crew encountered a large, metallic, oblong spheroid while climbing through 14,000 feet after departing Houston Hobby Airport. ATC urgently directed the aircraft to level off, reporting an unidentified target closing on their position that had been "popping up all day." The object, described as resembling molten mercury with a morphing surface, accelerated instantaneously from a stationary hover and departed at extreme speed. The encounter lasted approximately four seconds.
