Roof of a parking lot

This place is very close to the airport Tegel in Berlin. When I arrived I noticed a father with his son watching out for the planes coming in. The father had an app on his tablet and they had lots of fun checking out wether everything went according to the schedule.
I think I got a bit carried away by their enthusiasm…
