Among the people killed with a heat ray on Horsell common are <u>Martians</u>.
Horsell Common Landing Site was the first beachhead for the Martian invasion. The first projectile landed just after midnight on a Friday morning in June between the villages of Woking, Ottershaw, and Horsell in Surrey.
The projectile, first spotted by an astronomer named Ogilvy shortly after dawn on Friday, quickly became a subject of local interest because of its size and the crater it created upon impact. The tip of the was rotated all day and was completely dislodged from the inside just before 6 pm.
By this time, having cooled from the heat generated by the Earth's entry into the atmosphere, he had gathered a crowd of 200-300 people to see the first Maritan sightings. The sight of the unfamiliar and (to most people) uncomfortable Martian caused a general panic. Bystanders who fell into the crater were captured and killed by the emerging Martians.
