A fireball that streaked through the skies over East Coast which was described by viewers as the size of a “Cesna plane” and one of “the biggest, brightest, and most colorful ever!”, could have been a passing meteor.
Philly.com quoted NASA scientist Bill Cooke of the Marshall Space Flight Center as stating that the object seen might have been 5 feet in diameter and would have weighed more than 5 metric tons, basing the measurements on the reports of the brightness of the object. Cooke also estimates that the object was traveling at a speed of 33,500 m.p.h.
Cooke further estimated that the fireball’s energy was equivalent to about 100 tons of TNT and was capable of producing a crater 125 feet wide and 15 feet deep on impact.
