support operation (in an RWD-13) taking place on 17 December. The Galilee Squadron was formed at Yavne'el in March 1948, and the Negev Squadron was formed at Nir-Am in April. By 10 May, when the SA suffered its first combat loss, there were three flying units, an air staff, maintenance facilities and logistics support. At the outbreak of the war on 15 May, the SA became the Israeli Air Force. With its fleet of light planes it was no match for Arab forces during the first few weeks of the war with their T-6s, Spitfires, C-47s, and Avro Ansons. On 15 May, with the beginning of the war, four Royal Egyptian Air Force (REAF) Spitfires attacked Tel Aviv, bombing Sde Dov Airfield, where the bulk of Sherut Avir's aircraft were concentrated, as well as the Reading Power Station. Several aircraft were destroyed, some others were damaged, and five Israelis were killed. Throughout the following hours, additional waves of Egyptian aircraft bombed and strafed targets around Tel Aviv, although these raids had little effect. One Spitfire was shot down by anti-aircraft fire, and its pilot was taken prisoner. Throughout the next six days, the REAF would continue to attack Tel Aviv, causing civilian casualties. On 18 May, Egyptian warplanes attacked the Tel Aviv Central Bus Station, killing 42 people and wounding 100. In addition to their attacks on Tel Aviv, the Egyptians also bombed rural settlements and airfields, though few casualties were caused in these raids. At the outset of the war, the REAF was able to attack Israel with near impunity, due to the lack of Israeli fighter aircraft to intercept them, and met only ground fire. As more effective air defences were transferred to Tel Aviv, the Egyptians began taking significant aircraft losses. As a result of these losses, as well as the loss of five Spitfires downed by the British when the Egyptians mistakenly attacked RAF Ramat David, the Egyptian air attacks became less frequent. By the end of May 1948, almost the entire REAF Spitfire squadron based in El Arish had been lost, including many of its best pilots. Although lacking fighter or bomber aircraft, in the first few days of the war, Israel's embryonic air force still attacked Arab targets, with light aircraft being utilised as makeshift bombers, striking Arab encampments and columns. The raids were mostly carried out at night to avoid interception by Arab
