90 years after Loch Ness Monster first spotted, thermal drones survey Scottish lake in giant hunt this weekend

A view of the Loch Ness Monster, near Inverness, Scotland, April 19, 1934. The photograph, one of two pictures known as the 'surgeon's photographs,' was allegedly taken by Colonel Robert Kenneth Wilson, though it was later exposed as a hoax by one of the participants, Chris Spurling, who, on his deathbed, revealed that the pictures were staged by himself, Marmaduke and Ian Wetherell, and Wilson. References to a monster in Loch Ness date back to St. Columba's biography in 565 AD. More than 1,000 people claim to have seen 'Nessie' and the area is, consequently, a popular tourist attraction.

90 years ago, the old Drumnadrochit Hotel was the location a Mrs Aldie MacKay reported seeing a whale-like "water beast" in Loch Ness, a sighting that created the birth of a global legend. This weekend the Scottish hotel, reborn as The Loch Ness Centre, will be host to the biggest surface watch in 50 years as enthusiasts and technologists come together to explore the waters.

We better hope Nessie isn't disturbed by the sound of fast-turning propellers, since one of the technologies being tried this time will be the best thermal-imaging drones, with thermal infrared cameras.
