Alien landing

In a top secret operation together with the coastguard of the Dutch beach town Bloemendaal aan Zee a spacecraft appeared from nowhere on a bright summer day.
It silently hovered inches above sea level and landed ashore. To the astonishment of the sunbathers two aliens came out of the craft. They were very friendly and inquisitive, with a special attention for young children. After a few hours on the beach these sweet creatures vanished in the dunes, nobody has seen them since. The craft has been secured by the coastguard and is to this day still in their barracks.
