AFTER THE ACFT BOUNCED 3 TIMES THE PLT DECIDED TO GO AROUND & HE APPLIED FULL PWR. THE PLT FORGOT TO RAISE THE FLAPS FROM THEIR FULLY EXTENDED POSITION. THE ACFT OVERRAN THE RUNWAY'S END COLLIDING WITH A RWY LIGHT, 2 PARKED ACFT & A TRUCK, & IT CAME TO REST UPON IMPACTING A COMMERCIAL BLDG. WHICH HOUSED A FBO.
