In what direction may an R/C Rocket Boosted Glider (RBG) be launched in relation to the flightline?

The correct answer states that an R/C Rocket Boosted Glider (RBG) may be launched parallel to or away from the flightline. This is important for safety and operational efficiency reasons. Launching parallel to or away from the flightline helps to ensure that the rocket's flight path does not cross over areas where spectators or personnel might be located, thus minimizing the risk of injury or damage during the flight.

Launching parallel keeps the glider on a controlled path, allowing for better predictability in its trajectory and making it easier to manage recovery operations. Additionally, launching away from the flightline allows the rocket to ascend out of the crowd's area, further enhancing safety. While considerations may permit launching at different angles, any launch towards the flightline could compromise safety protocols established to protect observers.

Ultimately, the guidance to launch parallel to or away from the flightline is rooted in principles of safe rocketry practice, establishing clear areas for takeoff and ensuring that the flight path remains predictable and controlled.
