Remember the time a world record was set at the Imperial Hotel, in North Shore, Blackpool?
In May 1975, Blackpool skin diver Brian Foulds set the then world underwater endurance record – after staying under the surface for a total of 88 hours.
The previous record had been 50. In 2011, a Turkish man stayed underwater for a staggering 192 hours – more than eight days, in a record that still stands.
But back in 1975, Brian’s mammoth efforts attracted much media and public attention.
The 23-year-old electrician, from Bispham, had started his record attempt with amusement arcade proprietor Jim Whiteside. But Jim had to give in after just 26 hours underwater – the pain in his hands was too bad for him to carry on.
Fellow members of the Blackpool and Fylde branch of the British Sub-Aqua Club kept their round-the-clock watch.
After 88 hours, Brian was lifted out of the water on a stretcher and examined by the doctor.
One of his helpers told The Gazette he would have liked to try for 100 hours, but medical experts warned he could cause permanent damage to his skin by staying under for longer.
Every hour during the feat, a measuring tube and electronic recording thermometer – borrowed from Blackpool Victoria Hospital – was sent down to check Brian and Jim’s temperature, to make sure it did not fall below 36 degrees.
There were only allowed three hours’ sleep at a time, because inactivity would have caused a temperature drop.
A special piped air supply by compressor kept them breathing while they were dozing.
To alleviate the boredom – which was the biggest problem as they sat at the pool bottom – a battery-powered TV set was sent down in a sealed fish tank and headphones were provided for radio and piped music.
Brian and Jim were fed by “moon food” – dehydrated plastic-bagged goodies – sent from NASA.
When Brian emerged, he said only his hands and feet were sore, but the challenge had posed him with no real problems.
He said: “I feel great. I wish I was still down there.
“I’ve been diving for six years, so I’m used to it.”
