The Upside Down Ship Illusion

[Weather-history]

From John R Sherwood of the Royal Canadian Airforce, Ontario

"I witnessed a remarkable and rather amusing siight whilst on the coast of Labrador this summer (1932)

I was on meteorological work in connexion with the air mail service for the Imperial Conference in Ottawa. The air mail had to be transferred from the Empress of Britain in the Straits of Belle Isle to the aircraft, which flew it to Ottawa. At 8h on 17th August, this procedure was in progress and although it was perfectly clear and sunny where I stood on the shore, there was an extensive layer of fog at the scene of operations about three miles out and only the smoke of the Empress was visible above the layer. After watching for several minutes, I was startled to see the Empress above the fog completely upside down with her hull pointing skywards and her masts apparently resting on the layer of fog. The illusion lasted for about one minute and was perfectly clear in every detail when it finally disappeared and the ship came out of the fog in its normal position. "
