This World War II timeline of European Air Operations lists notable military events in the skies of the European Theater of Operations of World War II from the Invasion of Poland to Victory in Europe Day. The list includes combined arms operations, defensive anti-aircraft warfare, and encompasses areas within the territorial waters of belligerent European states.
September 1: The Luftwaffe begins operation Wasserkante as part of the invasion of Poland. The first air attacks against Warsaw start.
September 2: Single PZL.23B of the 21st Squadron of Polish Air Force bombs a factory in Ohlau. The attack represented the first Allied bombing raid to be conducted against a target in territory within the Third Reich.
September 3: Flying officer Andrew McPherson is the first RAF pilot to cross the German coast after Britain declared war on Nazi Germany. Flying a Bristol Blenheim from 139 Squadron, his mission is to identify German maritime targets around Wilhelmshaven.
September 3: The RAF launches its first raid of the war over Germany territory. Eighteen Handley Page Hampdens and nine Vickers Wellingtons are sent to attack the German warships moored at the Wilhelmshaven naval base. However poor visibility prevents the bombers from finding any targets before nightfall so they return.
September 4: The RAF launches another bombing operation against German shipping. Fourteen Wellingtons from 9 and 149 Squadrons attack Brunsbuttel and 15 Bristol Blenheims from 107 and 110 Squadrons raid Wilhelmshaven bay. Five Blenheims and three Vickers Wellingtons are shot down through a combination of Messerschmitt Bf 109s and flak. They become the first British aircraft casualties on the Western Front.
September 4: The first British airman to be taken prisoner was Sergeant George Booth, a RAF Observer from 107 Squadron. He was captured after his Bristol Blenheim was shot down over the German coast.
September 27: The Luftwaffe ceases its bombing campaign against Warsaw after its Polish garrison surrenders to German forces. Approximately 1,150 sorties were flown by a wide variety of aircraft, including obsolete Junkers Ju 52/3m bombers.
November 30: The Winter War between Soviet Union and Finland starts. Three hours after Soviet forces had crossed the border and started the Winter War, Helsinki is bombed. Throughout the war, the Soviet Union has the air superiority and several cities in Finland are targeted.
December 18: The first use of radar for defence (an "experimental Freya radar") gave warning of RAF bombers near the German Bight as they made an attack on Wilhelmshaven.:20 However the German fighters were not permitted to intercept until visual confirmation was made - the bombers were attacked after they had dropped their bombs.
April 21: A bombing raid on Norway kills the first American military officer killed in World War II.
May 15: The RAF lost the 100th of its France-based bombers. In 72 hours, it had lost half of its offensive force.

August 21: 12 B-17's are dispatched to bomb the shipards in Rotterdam, Netherlands but is aborted due to an attack by Bf 109s and Fw 190s; 1 bomber is damaged; Lack of proper coordination with the Spitfire escorts is a major factor in the failure of the mission.

September 9: The Luftwaffe's KG 100 bomber wing is involved with the world's first successful use of a precision-guided munition in modern military history, through their sinking of the Italian battleship Roma, using the Fritz X armored gravity-propulsion PGM munition.
October 10: As a result of the June "surrender/escape" of a 100 BG B-17, out of the 13 B-17s of 100 BG attacking a railyard in Münster, only the B-17F of Robert Rosenthal survives to return safely to RAF Thorpe Abbotts in England.
November 1: A Combined Bomber Offensive progress report estimates that 19/19/9 German towns & cities have been virtually destroyed/severely damaged/more effectively damaged – another report claims 10% of German war potential had been destroyed

From the Till report of June 1945: "The Intelligence Officer with 83 Group RAF has admitted on two occasions; first to Lt H. F. Ansell of this Team (when it was confirmed by a Wing Commander present), and on a second occasion to the Investigating Officer when he was accompanied by Lt. H. F. Ansell, that a message was received on 2 May 1945 that these ships were loaded with KZ prisoners but that, although there was ample time to warn the pilots of the planes who attacked these ships on the following day, by some oversight the message was never passed on... From the facts and from the statement volunteered by the RAF Intelligence Officer, it appears that the primary responsibility for this great loss of life must fall on the British RAF personnel who failed to pass to the pilots the message they received concerning the presence of KZ prisoners on board these ships."
