The third raid, which lasted 20 minutes, was carried out by a small group of fighter-bombers flying at very high altitude. As in the two morning raids on the airport suburb of Gia Lam, the targets were not immediately known. From the columns of black smoke rising in the sky, it was not clear whether the targets were inside the city or on its immediate outskirts. Both the earlier raids came in two waves and lasted about 15 minutes. The first sent up plumes of smoke from a target area that appeared to lie north of the capital's commercial airfield, two miles north-east of the Red River. Three aircraft were seen falling in flames, two from missile hits and the other from conventional anti-aircraft fire. The second raid was farther to the east. It sent up a thick black column of smoke that appeared to come from one end of the airfield.
