THE ACFT COLLIDED WITH THE GROUND IN A HIGH SPEED DIVE AND TOTALLY DISINTEGRATED. IMPACT CREATED A 7' CRATER AND MATERIAL BLEW OUT FOR 100 YARDS. THE ENGINES WERE RECOVERED AT THE 14 FT LEVEL IN THE CRATER. THE ACFT TOOK OFF AT 2215 FROM BAYTOWN TX. AT 2334 RADAR AND RADIO CONTACT WAS LOST. AT NO TIME DID THE PLT INDICATE THAT HE WAS HAVING ANY DIFFICULTIES. AS RADAR CONTACT WAS LOST THE RETURN WENT INTO COAST MODE FOR 8 SWEEPS OR 38 SECONDS.
