Airbus just improved its supersonic jet. Lets check that out.
In July earlier this year, Airbus received a patent on a supersonic aircraft that could reach New York from London in 1 hour. This week, Airbus filed a patent application on an important improvement to their supersonic aircraft.

The supersonic aircraft has a rocket engine at the back of the fuselage. It also has two turbojets laterally arranged near the rear of the fuselage. Once the aircraft climbs to a certain altitude, the turbo jets are powered off and the rocket engine is ignited at full power causing the aircraft to travel vertically like a rocket at supersonic speeds. Because of this vertical trajectory, the energy of the supersonic boom is dissipated in all horizontal radial directions and does not encounter the ground. At this point of time, the turbo jets cause lot of drag. Therefore, flaps placed in front of the inlets of the turbo-jets are activated. The flaps cover the inlets, thereby reducing the drag considerably.
After reaching a very high altitude, the aircraft curves into a horizontal trajectory at which point the rocket engine is powered off and closed by a door to make it streamlined. Thereafter, the flaps can be retracted and the turbojets can be ignited to propel the aircraft horizontally at supersonic speeds.
The fact that there is another patent application on the same technology, it indicates that Airbus is seriously working on this aircraft. So expect to have this in use quite soon.

Patent Application No. 20150344158
Title: SPACE AIRCRAFT
Assignee: AIRBUS DEFENCE AND SPACE SAS (Les Mureaux, FR)
Inventors: Ferreira, Eugénio (Toulouse, FR); Prampolini, Marco (Chambourcy, FR); Coraboeuf, Yohann (Merignac, FR)
Application Number: 14/763299
Publication Date: 12/03/2015
Filing Date: 01/17/2014
International Classes: B64G1/40; B64G1/14
Abstract: According to the invention, said space aircraft comprises, at the front of each of the air inlets of the turbo engines, a mobile flap that can move, in both directions, between a first position for which said flap opens said air inlet and a second position for which said flap prevents air from entering said air inlet.
