Alan Stacey's fatal accident during the 1960 Belgian Grand Prix was caused when a bird hit him in the face on lap 25, causing his Lotus 18-Climax to crash at the fast, sweeping right hand Burnenville curve. According to fellow driver Innes Ireland's testimony in a mid-1980s edition of "Road & Track" magazine, Ireland stated that some spectators claimed that a bird had flown into Stacey's face while he was approaching the curve, possibly knocking him unconscious, or even possibly killing him by breaking his neck or inflicting a fatal head injury, before the car crashed.
