MITCHELL AIR FORCE BASE, N. Y., Sept., 11--An Air Force jet pilot reports sighting a mysterious round object speeding about 900 miles per hour over the New Jersey coastline. 

The report came yesterday from Lt. Wilbert S. Rogers, 28, attached to the Air Force base at Dover, Del. 

Lt. Rogers told officers here about the strange object after landing with Capt. Edward Ballard, Jr., as his passenger on a flight from Dover here in a T-33 jet trainer. 

"I don't know whether it was a flying saucer," Lt. Rogers said. "But it sure was something I've never seen before." 

The World War II veteran from Columbia Pa., was reminded that various units of the armed forces have knocked down reports of "flying saucers" and that most have been explained as weather balloons. 

"This couldn't have been a balloon, because it was descending" he said.  "And besides, no balloon goes that fast." 

Here's Lt. Rogers' description of what he and Capt. Ballard saw: 

While flying over Sandy Hook, N. J., at 450 miles per hour at an altitude of 20,000 feet at 11:35 a.m. (10:35 EST) yesterday, they spotted a white or silver circular object below them at about 12,000 feet altitude moving inland.  The object appeared to be about the size of a fighter plane. 

As they followed the object, it moved in an arc from Sandy Hook to Red Bank, which is inland in New Jersey, then out to Asbury Park on the coast and out to sea in southeasterly direction. 

The object disappeared after the Air Force plane had followed it for about 30 miles, getting as close as 8,000 feet to it. 

The object did not seem to be fleeing from the Air Force plane, as its speed appeared constant. It had dropped to about 2,000 feet altitude before the two men lost sight of it. 

<>Capt. Ballard left for Dover to report on the occurrence to the 148th Fighter Interceptor Wing, Lt. Rogers said.
