For 20 minutes, emergency services at Peterborough, Cambridgeshire, waited nervously on the ground, looking up to the sky toward Sibson Airfield. A skilled pilot had radioed in that something had gone wrong with his replica plane and the landing gear was not releasing. The pilot circled overhead, burning fuel as the fire and medical teams assembled below, ready for any issues that might arise from this one-man plane's emergency landing. The replica is a Supermarine Spitfire, a British fighter plane that the Royal Air Force used during WWII. This plane is built to scale from what's referred to as a kit plane or amateur-built aircraft. The safety of these planes is not up to the level of certified aviation planes, although the rate is still fairly low. As you can see here, having the proper flight training goes a long way.
