In order to qualify for the record, Bill must fly over both poles and also have a distance 120 - 180 degrees between
lines of longitude, which is why he flew so far East on the way to Brazil. It's a closed route (no gaps) and must
be declared before departure. You can look up all the rules, requirements and records.
