The Pull allows the formation to quickly gain altitude without the formation breaking apart. It’s not a maneuver performed during shows, since the planes are already at the right altitude prior to entering the display area. The formation does frequently perform this maneuver on Sunday mornings during training.
The departure route from Rotterdam The Hague Airport to Hook of Holland is situated at 1000 feet (about 300 meters). More than high enough to fly safely, but for practicing formations we prefer to start a bit higher. The Pull brings the formation to 1500 feet, just about 450 meters. This allows for more leeway to correct any mishaps. Besides, the higher we fly, the less loud we are for people on the ground. We do like to entertain you on Sunday morning, but we don’t like to ruin your lazy morning, and six planes do produce quite some noise!
