When Troy Bradley and Leonid Tiukhtyaev land in Mexico on Saturday in their large helium balloon Two Eagles, they will have broken at least one and possibly two world records.
After setting out from Japan on Sunday and flying across the Pacific, the duo are on course to set new records for longest distance flown as well as longest duration in a helium balloon, the BBC reports.
Bradley and Tiukhtyaev needed to surpass a 1981 distance record of 5,208 miles by 1% (which put their target at 5,260 miles) in order to lay claim to the first record, which they did on Thursday according to a tweet from the team’s account. The record for longest duration, set in 1971, is 137 hours, five minutes and 50 seconds.
The American-Russian pair had originally planned to land in the U.S. or Canada, but bad weather forced them to change course.
