65 Testing ProcessVehicle handler. Inflates the balloon to the standard size, transfers it to the starting line and releases it when the starter says, “go.”Observer/recorder. Holds the template or string to measure balloon size. Calls “stop” to the timekeeper when the vehicle stops rolling. Records distance traveled and time or relative speed.Starter/timekeeper. Watches the clock and reports time if the team is recording time, checks to see when the testing floor is clear, and says “clear” when it is, then “ready, set, go.”
