Bob Reid obituary

My friend Bob Reid, who has died aged 92, was a cosmic ray physicist who studied these mysterious particles in Jamaica, on the moors of North Yorkshire and at the South Pole.

Bob also had a fascination with boomerangs and was a member of the British Boomerang Society. In December 1988, while searching for cosmic rays from Supernova 1987A, he threw one around the South Pole, which technically stayed aloft for 24 hours and nine seconds as it travelled through 24 time zones.
