Correct! The cooler, denser air in the balloon has made you heavier.
You've avoided the thunderstorm and caught the easterly current at 1,524 m
(5000 ft). But there's no time for a nap now! If you stay on this course,
you'll be heading right over Manila airport—not a good idea! You need to
catch the southerly current at 2,286 m (7,500 ft), which will take you directly
over Australia. What are you going to do?
