Translation of determinism in German

On the first day in Hanoi, we wanted to explore the town. It was the former capital of the North and today it is the capital of the entire country. There are tons of monuments and governmental buildings.
The next day we had to take the bus in order to get back to the airport in Calama. When we arrived at the airport was empty and no counter was open yet. We had to wait for 4 hours.
