Pilots Attempt Record-Breaking Balloon Trip Across Pacific

Pilots try to break records for distance and time in the air.

— -- Two pilots are trying to break world ballooning records as they begin a trip across the Pacific Ocean.

"This is a very coveted record and, hopefully, one that's going to stand for a long, long time," Mission Control Director Steven Shope said.

They will make the dangerous, 5,208-mile trip across the ocean with limited sleep and access to oxygen in a small capsule. Temperatures are expected to be in the 50s.
