It affects drag and supersonic flight characteristics, which is why supersonic aircraft generally have long noses.
The Harrier can't fly supersonic in level flight or fly long distances.

The Tupolev Tu-144 holds the title for the first supersonic passenger flight, ahead of the Concorde. However, the Tu-144 also holds the dubious distinction of being the first to end supersonic passenger service, lasting only 55 flights.
Supersonic Transportation is commercial flight by means of a supersonic vehicle. The Concorde was probably the most famous super sonic jet in history and flew commercial flights across the Atlantic. Its final flight was on November 26, 2003. Currently, there are no Super Sonic Transportation services available to the public.
