"Gaenicke said the first plane that contained the two people who were killed was on the ground; the second plane was circling and was attempting to land and collided with the other plane.
Both planes were home built aircraft. The plane that was struck on the ground was described as an RV-8; the second plane attempting to land was described as a Velocity aircraft.
This afternoon, Gaenicke explained how the accident is believed to have occurred. He said the Velocity aircraft landed at a high-rate of speed and was coming up on another aircraft. The pilot attempted to do a go-around, a maneuver where he attempts to add power to take off again. While doing that, the pilot veered off into a median between the runway and taxiway and struck the RV-8.
