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]
LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) was a 36-month European FP6 study to examine ways to produce engines for a Mach number 4-8 hypersonic flight aircraft. The project ended in April 2008. [1] It was funded by the European Commission research and development fund (rather than ESA), and cost 7 million euros. [2] [3]
Higher speed designs using compression lift, waveriders, remain an interesting possibility for hypersonic vehicle designs, although only testbed models have been flown. [1] The Boeing X-51 (Waverider) also uses compression lift.

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 ...
