The final planned version in the T-Class range, the T-21 airbus is designed for extended trips carrying larger groups of passengers. A huge fuel capacity gives the T-21 a much greater range than any other model in the line, and the interior was designed to give passengers plenty of room so that they would not feel cramped on long-haul journeys.

While it is the most expensive model in the T-Class range (making use of aluminium instead of steel) the T-21 has still proven popular with tourism companies and some can even be found working as private hire taxis.

As with others in the range use of repulsor technology keeps the T-21 off the ground and locked in place when not in use.
