About the distance of the Dover Strait (the narrowest part of the English Channel, the strait between Great Britain in the United Kingdom and France)...
The Mandela Effect about the distance of the Dover Strait (the narrowest part of the English Channel, the strait between Great Britain in the United Kingdom and France) has flip-flopped. It should have been at least 145 kilometers, but after a period when it was 50 km, now it is a mere 20 km apart. Yet there are also many stories of people having seen old TV programs that planned challenges to swim across.
This case is part of the Mandela Effect case database based on "The Window of Opportunity: A Guidepost to the Mandela Effect — The Ultra-Secret X-Files" by Aoyama Takuto.
