At 11:10am, SBD Dauntles dive bombers from VS-2 began dive bombing and were intercepted by the fighters and missed the carrier which maneuvering and one Dauntless was shot down by the Zero. Shoho launched three additional A6M2 Zeros as other SBDs began dive bombing at 11:18 and scored two hits with 1,000 lbs bombs on the flight deck that exploded inside the hanger igniting fuel and aircraft. After his attack, Lieutenant Commander Robert E. Dixon, commander of VS-2, radioed his famous message to the American carriers: "Scratch one flat top!" US Navy Admiral Fletcher aboard USS Yorktown.
