Think you know Europe? See it you can land a plane in the right city in the time given. Just click on where you think the city is. Three rounds - Find a city first with dots for cities and country borders shown; then just country borders; and then no borders just the whole continent. Humbling and funny.
I didn't submit my name and email at the end (it's legit but I am sure it's a Lufthansa marketing ploy to get your email address).
