I decide to go on a trip around the earth in my jet which goes 25,000 mph cruising speed. I take off from Bogota, Columbia on Monday April 25th at 9am going east into the stratosphere. I continue going around the planet 24 times and land at Bogota 9am April 26th. However everyone else tells me the date is May 19th. How did I lose 23 days? Did I go back to the future?
