A launch platform may include sensor(s) that detect movement of a platform that supports an aircraft. The platform may move in response to departure of the aircraft from the platform. In response to a change in a signal or signal state of the sensor(s), a timer may initiate timing of a race. The timer may be stopped in response to a second or later change in a signal or signal state of the sensor(s). A target may extend above the platform and, when impacted by an aircraft, may cause the second or later change in the signal or signal state of the sensor(s). By using the target, the aircraft may stop the timer by impacting or colliding with the target rather than landing on the platform. In some embodiments, the launch platform may be configured to track time for a race that includes a predetermined number of laps.
