Frankfurt (Main), Germany: Counting nearly 61 million passengers FRAPORT is one of the busiest airports of Europe. Only topped by London Heathrow Airport (75 million passengers in 2016), Charles de Gaulle in Paris (66 million) and the Amsterdam Schiphol Airport (64 million).
While it is the largest and busiest airport of Germany it’s still a place where prototypes are tested. The following spectacular landing of a prototype plane didn’t went as smooth as planed. It was captured by workers on the roof of one of the terminals.
While a plane is surely able to fly autonomous guided by autopilot it’s pretty uncommon for a plane to have to go to the loo.
