In 2017, a pilot flying over Western Australia noticed an SOS made of rocks in a remote location. Realizing that somebody could be stranded in this hostile environment, the pilot reported it to police, who launched an investigation.
The mysterious SOS was later revealed to have been created four years earlier, when a couple became stranded on their yacht in Swift Bay. They survived on meagre rations before being rescued by a passing yacht days later.
Despite this SOS signal not aiding their survival, it was certainly a smart way to increase their chances of rescue, however not all SOS stories have such a positive and logical conclusion, so here are Chilling SOS Calls That Have Never Been Explained.
In the Akita prefecture of Japan, emergency calls from landlines have recently been proving such a mystery that local firefighter chiefs submitted a letter of enquiry to the local phone company to begin an investigation. In 2020, emergency responders were called out 9 times to properties where residents were unaware that their landline phone had dialled the emergency services.
The calls didn’t contain an audible language, but were described as robot-like noises by those that heard them. Due to them being considered ‘mute emergency calls’ firefighters were dispatched to the locations where the calls originated from, only to find bemused residents with no idea why the fire service was interrupting their dinner. Over half of these calls were made when residents were not even home!
