[Updated 6/28: The World View KFC launch has been rescheduled for June 29. The launch window opens at 8 a.m. EDT]
The launch of a stratospheric balloon carrying a fast-food chicken sandwich to the edge of space has been delayed until Thursday (June 29).
The sandwich's four-day flight is a promotional stunt for Kentucky Fried Chicken, but it will serve as a valuable test for World View Enterprises, the company developing high-altitude balloons for applications ranging from weather monitoring to tourism. This is the first long-duration flight of the company's Stratollite balloon vehicle.
The flight was delayed due to weather conditions, a public relations representative for World View Enterprises said in an email obtained by Space.com. The balloon will reach altitudes of between 60,000 and 75,000 feet (18,300 and 22,900 meters) above Earth, or about twice as high as commercial airliners fly.
