Operation Bodenplatte was the Luftwaffe's last-ditch attempt at grounding allied air forces and halt the eastward march of the allies. Multiple squadrons took off at dawn on 1 Jan 1945 to attack allied bases in Belgium and The Netherlands, the morning after many allied pilots had been celebrating for New Years Eve.
At Asch Airfield, a flight of P51s were getting ready to take off when their airfield was attacked by multiple waves of FW-190s and Bf-109s. You'll play as one of these Mustangs, and defend the airfield from both aircraft types in the winter morning sun.
