The storm-like blips left the National Weather Service in a state of confusion since it wasn’t raining in the region, the Courier and Press newspaper in Evansville, Ind., reported.
A local TV meteorologist tweeted out that an unnamed pilot at the Evansville Regional Airport in Indiana said the fog was chaff – radar-jamming material sometimes released during training exercises – from a military C-130 aircraft.
“Information from a pilot appears to confirm that chaff was the mysterious radar echo that traversed #tristatewx late Monday afternoon/evening. Pilot was told by EVV Air Traffic Control that chaff was released by a military C130 northwest of Evansville. @NWSPaducah,” WEHT-TV meteorologist Wayne Hart tweeted.
If the blips were indeed chaff from a military plane, no military installations in the area are claiming it as theirs.
“Whatever aircraft it was, it was not a Scott Air Force Base craft,” Master Sgt. Thomas Doscher said Tuesday morning.
A spokesperson for Fort Campbell in Kentucky said he didn’t know any operation involving a C-130. He added that if such a plane did originate from the Army base, it would have been involved in a secret special forces exercise.
The Federal Aviation Administration and the Evansville airport did not immediately respond to Fox News requests for comment early Wednesday.
