How do people feel about the new supersonic plane? A sonic boom every five minutes near Heathrow!

They could be crossing the country from Europe. The article says there will be about 2000 of them. I heard sonic booms in Osterly Park pre concorde testing.

How long into the flight to they reach supersonic speed? I assume this will be achieved well after takeoff once they are at cruising altitude.
