What was found
ABOUT 25 MILES OUT, ENROUTE, MEDICAL CREW INFORMED ME THAT THEY HAD HEARD A LOUD SOUND FOLLOWED BY A "THUD" THAT THEY FELT UNDERNEATH THE LT SIDE OF THE ACFT. DID NOT HEAR OF FEEL OR HEAR WHAT THEY HAD JUST EXPERIENCED, ASKED THEM TO SHOW SPECIFICALLY WHERE THE ABNORMAL NOISE WAS COMING FROM. IT LOOKED LIKE IT WAS AROUND THE LT MLG. TURNED THE ACFT BACK TOWARDS THE NEAREST AIRPORT, NOTIFIED THE COMMUNICATIONS CTR AND LANDED WITHOUT FURTHER INCIDENT.
