The U.S. Coast Guard says four pyrotechnics that went missing in Lake Michigan have now been accounted for. It shared the update Wednesday in a post on X, citing information from the U.S. Air Force.
They were reportedly conducting a joint exercise in Milwaukee earlier this month, when four phosphorous pyrotechnics failed to activate when entering the water. One was reportedly found Monday by a lifeguard at Montrose Beach in Chicago. That prompted the Coast Guard to issue a warning to beachgoers.
The flares produce red smoke and a flame that can reach temperatures of 2,900 degrees.
