On March 24/25th the nuclear summit will be held in The Hague, Netherlands. For this, a lot of the world leaders will arrive at Schiphol Airfield. One of these leaders is the president of the United States. As you probably know the president has several aircraft to his disposal. A 747 Boeing called Air Force One when the President is on board. And a helicopter called Marine One when it carries the president.
Today I was at the office at Schiphol when we got disturbed by a big group of helicopters. They flew right over our building, did a quick touchdown at the airfield and flew back.
When looking closer, it appears to be the Marine One and a big military convoy.
