Battle of Britain Day 37. Fine weather yields the first day of really big raids on British airfields. German bombers and fighters from Norway and Denmark cross the North Sea to bomb RAF airfields in the North of Britain. At noon, they are met by RAF fighters. Simultaneously, a huge formation of 1100 Luftwaffe aircraft cross the Dover Straits, then splits up heading for various airfields. RAF squadrons scramble, giving rise to dogfights over Kent and the English Channel. Numerous airfields have damage to planes, hangers and runways. Radar stations at Rye, Dover and at Foreness are also knocked out. At 6.50 PM, Messerschmitt Bf110s bomb South London airfield at Croydon by mistake. Many Bf110’s are shot down by RAF fighters, crashing in this suburb of London (60 civilians killed, 120 wounded). Despite taking a heavy toll on RAF installations, Luftwaffe loses 161 aircraft (mostly bombers) while RAF losses are 34 fighters and only 18 pilots killed. http://www.battleofbritain1940.net/0026.html http://www.raf.mod.uk/bob1940/august15.html
