Peter Leach quite rightly derides NASA working on commercial supersonic flight. However, there is one potential important customer: the US military, which probably lacks the expertise to develop large supersonic aircraft (Letters, 10 February).
I can imagine it needing these to move specialist personnel and mission-specific equipment from a central base in the US to a “hotspot” at short notice. This would seem to be more cost-effective than relying on having numerous supply depots with a broad range of equipment and personnel around the world.
