ABOUT 10 MIN AFTER TAKEOFF AT 1005 MDT, THE PLT WAS CLEARED TO CLIMB TO FL 190. THIS WAS ATC'S LAST COMMUNICATION WITH THE ACFT. AT 1030:39, THE CONTROLLER ATTEMPTED TO CONTACT THE PLT TO ADVISE THAT HE HAD LOST RADAR CONTACT & TO RECYCLE THE TRANSPONDER & SQUAWK 6062. THERE WAS NO RESPONSE. TWO WITNESSES REPORTED SEEING THE ACFT JUST BEFORE IT IMPACTED THE GROUND. ACCORDING TO THEM, THEY SAW FIRE &/OR AN EXPLOSION BEFORE IMPACT & ONE WITNESS REPORTED THE ACFT BROKE UP AFTER IT CAME BELOW AN ESTIMATED 1000 TO 1200 FT CEILING. HOWEVER, THE WRECKAGE WAS SCATTERED OVER A 2 MI AREA. AN EXAM REVEALED EVIDENCE OF A CATASTROPHIC IN-FLT BREAKUP FROM OVERLOAD WHICH INCLUDED POSITIVE OVERLOAD OF BOTH WINGS. RADAR DATA SHOWED THAT JUST BEFORE RADAR CONTACT WAS LOST, THE ACFT'S SPEED VARIED BETEEN 221 & 272 KTS, HEADING VARIED FROM 072 TO 014 DEG & VERTICAL VELOCITY VARIED FROM +300 TO -2400 FT/MIN. THUNDERSTORMS, TURBC, RAIN & CLD TOPS TO 25,000' WERE REPORTED. PROBABLE LGT TO MOD ICING IN CLDS ABOVE THE FREEZING LVL (14,000'). ACFT HAD WX RADAR ABOARD.
