Landfall in Europe

The balloon has crossed Portugal and Spain and is heading for the Bordeaux region of France (a personal favourite of mine!). It is only 80 metres lower than it was a couple of days ago, having climbed somewhat since yesterday. I surmise this is because we've moved into an area with higher barometric pressure. If the on-board altimeter were a barometric type, that wouldn't matter, but using GPS to measure altitude means that the actual altitude will be reported, which will be at the atmospheric density where the balloon's buoyancy and weight are at equilibrium.

Now we can see how many countries the balloon can visit during its lifetime. As far as I can tell, this is a record duration flight of all of them so far.
