On arrivals day at Fairford for the Royal International Air Tattoo, I was up at the park and view west location. The Czech Air Force brought in a couple of W-3A Sokols and parked them on some pads built near our location. They were then preparing for a practice display. Meanwhile, some of the crew were left on the grass waiting for something to do. I thought it was quite amusing seeing them hanging around and looking so bored while so many arrivals were underway around them.
