Showing the way they went - for iPad/Mac/PC
10 episodes - English - Latest episode: about 14 years ago -Hot air balloon rides have become a popular celebration treat. But do they really just drift with the wind? Investigate the meticulous planning needed for round-the-world flights. Learn how journeys are monitored and measured, and discover how pilots merge mathematics and geography while high above the ground. This material forms part of the course MU120 Open mathematics.

Spherical geometry
May 19, 2009 01:31 - 10 minutes - 120 MB VideoThis track shows us how a hot air balloon is produced and how the application of spherical geometry is imperative when planning a round the world flight, and what programmes and software packages are used to make these calculations.

Great-circle distance
May 19, 2009 01:29 - 3 minutes - 39.4 MB VideoGreat-circle distances might be the shortest way to travel, but they are not always the easiest. We also look at how lines of latitude aren't great-circles and that permission must be acquired to fly over many countries.
