The A2 design does not have windows. The heat generated by the hypersonic airflow over the body puts constraints on window design which would make them too heavy. One solution Reaction Engines proposed was to install flat panel displays, showing images of the scene outside. [1]

Both these missions are funded by the US Defense Advanced Research Projects Agency to help develop hypersonic technologies and to demonstrate its effectiveness. [6] Under the original plan, HTV-1 was to feature a hypersonic lift-to-drag ratio of 2.5, increasing to 3.5-4 for the HTV-2 and 4-5 for the HTV-3. The actual lift-to-drag ratio of HTV-2 ...
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
The second phase of the Hypersonic Weapon System development was to perform a set of flight tests with a series of boost-glide Hypersonic Technology Vehicles (HTVs). [12] HTV-1: a low performance hypersonic glider, originally planned to fly in September 2007, now canceled because it was found not possible to manufacture the leading edges. [13]
