A Tucson-based aerospace company has rescheduled its KFC-sponsored high-altitude balloon launch.
World View plans to launch the KFC Zinger sandwich into the stratosphere at 5 a.m. Thursday.
The mission is dubbed as history's longest controlled stratospheric balloon flight with a commercial payload.
Scientists will study the sandwich after it returns to earth for telemetry data.
