The National Stadium in Warsaw, Poland, played host to the first Professional Windsurfers Association indoor competition in eight years last weekend. To accommodate the event, 792,516 gallons of water was poured into a specially built pool. It took approximately 40 hours to fill it up. In the end, the pool was 295 feet by 108 feet. To create waves, 34 fans generated winds up to 43 miles per hour.
Here are a couple of photos of the event and pool, which could accommodate 20 M-16 figher planes, according to PL 2012+, the company that manages the stadium.
