Student pilot Henry Charles Salvatori and his flight instructor Michael Francis Mergen (NamUs #MP102343) have been missing since their Cessna 152 took off from Palm Beach International Airport on January 24, 1990. The two men flew out of Palm Beach at 7:23 p. m. , in clear weather with three hours' worth of fuel. They were on a training flight en route to Palm Beach County Park Airport in Lantana, Florida. They didn't file a flight plan or tell anyone where they were going. They were seen practicing landings at Lantana, but they never returned to Palm Beach International. The plane may have crashed into the Atlantic Ocean.
