You should not expect civilian aircraft like A-350,380 or Boeing 747/787 or anything like it (unless they're in military service).
If you wish to see these civilian aircraft, I advice you to go to the Farnborough Air Show, which is the week after the Air Tattoo.
The German president flew to Weeze this morning, (by Luftwaffe Global) for a visit to the city of Kleve. Afterwards, he and his company flew with both Cougars to the barracks in Apeldoorn. He returned to Weeze in the afternoon.
Is there any info on when Obama will depart to, and arrive from Kortrijk? And is it expected that he will fly from Brussels Airport, or from a landing zone closer to his hotel?
