Well today was a lovely day, and while we stepped outside the house for a nice bicycle ride, I heard a sound that first puzzled me a bit and then immediately I recognized it. The very first thing in my mind said "helicopter" but two seconds later I realised it was something else:

The DC-3 of the Dutch Dakota Association !!!!
Gotta love that sound !!! And man what a beautiful sight to see it "glide" by on a gracious speed at an altitude of about 500 meters !

I checked their site and it turned out that they were doing "rounds around Rotterdam" today. Since I live very close to the largest accumulation of windmills in the Netherlands (Kinderdijk), I understood that they were flying over them to show it to the passengers on board.
The flights were about 90 euro for about half an hour flight (incl. start and landing) man, I definitely am going to do that next year !
The plane has been in restoration for 12 (!) years. A rep of Boeing/McDonnell Douglas mentioned that the last DC-3 was built in Holland, apparently impressed by the result.
I think there's only one plane that I would rather see fly over (or fly in!) and that's the Conny that they are restoring now in Lelystad:
