On the fourth of January 2020, Simon Halliday had travelled to the diving location known as Lancaster Hole with two buddies. This is a dive Simon had done before and he wanted it to be a solo dive which according to him would take no longer than three hours. Four hours passed and Simon never showed up. They contacted Cumbria police and a cave rescue organisation was contacted. Up to 40 members and divers from the Cave Diving Group were claimed to have responded at the time to help in the search for Simon. The search was on, but it didn’t take them long to sadly find their missing friend. Hallidays body was found 14 minutes and 60 meters into the underwater passage.
