The Classic Space Federation is not just about sleek fighter and exploration ships. Sometimes just getting crews where they need to be, and when it comes to shuttling personnel, one of the most reliable workhorses is the LL-445 "Mayfly" designed by the reveered Doctor Sinister.
The double wing design was chosen for aerodynamic advantages in atmospheric operations, and to hide the large fuel tanks.
Its design builds upon the LL-444 fighter, and it's no surprise that they look very similar.
The LL-445, however, has much increased carrying capacity, allowing it to carry either a pilot and five passengers, or a significant amount of essential supplies.
The Mayfly is popular among crews, especially after the incident on one of the Kroktal moons, which the crew attribute their survival to the sturdy design of the craft.
