Saw this on TV last night, dont know if its been done before but couldn't find it. Reaction Engines A2 - Wikipedia, the free encyclopedia
Looking at the specifications it could be quite a Plane. snip "The vehicle is intended to have about 12,430 miles (20,000 km) range and good subsonic and supersonic fuel efficiency, thus avoiding the problems inherent in earlier supersonic aircraft. The top speed is projected to be Mach 5+. It calls for the use of liquid hydrogen as a fuel, which has twice the specific impulse of kerosene, and can be used to cool the vehicle and the air entering the engines via a precooler."
With the increased range it would be able to avoid some of the problems encountered by Concord due to sonic boom problems by flying to & from Australia over the Arctic & Pacific!

It might actually be easier to track a body in space (after all, Nasa do it all the time) than a submerged submarine deep in the ocean. So perhaps not a credible deterrent. Plus there are treaties about not having nuclear weapons in space.

We could keep a supply of scousers in them and threaten to drop them on other countries.

Been waiting for this one since I was a kid. Infact we Brits have been looking into the concept since the late 50's

Great book British secret projects. Hypersonics,ramjets an missiles. Was going to say treat yourself for Christmas but they are going for £65 quid on Amazon now. Still here is a link to the series. Great books.Amazon.co.uk: british secret projects

I heard a few companies were trying to develop supersonic business jets, including Tupelov who are basing their design on a Soviet era supersonic bomber. Could reduce turnaround times to zero with inflight refuelling and a bomb bay that could be opened to drop punters onto the terminal without having to land. I can see Ryanair buying a whole fleet of these aircraft.

Dropping over-emotional people with little or no sense of dress outside of the miracle that is polyester?

We wont need to drop them in. All we need to do is to say that the match is about to start and they will just push their way in.
