AT APPROXIMATELY 1335 LOCAL TIME, WHILE CONDUCTING ROUTINE SURVEILLANCE OF THE 2011 SELFRIDGE AIR SHOW, INSPECTORS FROM THE EAST MICHIGAN FLIGHT STANDARDS DISTRICT OFFICE (EMI FSDO) OBSERVED AN INDIVIDUAL FALL FROM AN AIRCRAFT. THE INDIVIDUAL WAS ATTEMPTING TO PERFORM AN AERIAL TRANSFER FROM AN AIRPLANE (N49739, 1943, BOEING A75N1 PT17) TO A HELICOPTER (N7505B, 1985, SCHWEIZER, HUGHES 269C). INSPECTORS WERE NEAR THE AIR BOSS CONTROL TRAILER LOCATED NORTHEAST OF THE DESIGNATED AEROBATIC BOX. THE AIRCRAFT PASSED FROM NORTH TO SOUTH BY THE CONTROL TRAILER. BOTH AIRCRAFT APPEARED TO BE WITHIN THE DESIGNATED AEROBATIC BOX AT THIS TIME.
