If you're looking for some good decent spotting locations at BRU, check out http://users.telenet.be/PowerCorruptionLies
--> ENTER-->AVIATION-->BRU Airport. There you'll find a link to a page containing most known spotting locations at BRU and some links to other good spotting locations.
By the way, I wont be able to make it on both dates:
July 16 and 17th: I'm still in Lissabon
July 20th: MY FIRST CESSNA FLIGHT! I'll even fly the bird myself
Maybe I'll try to make a nice low pass at BRU, but I don't think the instructor nor the other pax will like this
On the other hand, we'll be flying from Grimbergen airfield, which is pretty close to BRU...
