On the beach of Peter and Paul fortress dozens of space rockets will take off 

Copies and sport models of space shuttles, airplanes and rockets will go surf the "stratosphere" from the Peter and Paul Fortress in celebration of the Day of Cosmonautics. Models will be presented at noon after a loud cannon shot.

The launch of rockets, made by children and rocket enthusiasts, will be held on April 13 at 12:00. Traditionally, just after the midday cannon shot, dozens of ships and rockets from sporty and demonstration models to exact copies of supersonic aircraft will take off.

This year’s celebration will also be devoted to the 80th anniversary of the first cosmonaut Yuri Gagarin and the international Day of Cosmonautics.
