Reaction Engines plan Mach 5 Airliner
What is? writes "A British company has designed an eco-friendly airliner that could make a trip from London to Sydney in under five hours. Reaction
Engines has received funding from the
European
Space Agency to design the plane as part of the
Long-Term
Advanced Propulsion Concepts and Technologies project. The
A2
airliner would be capable of carrying 300 passengers at speeds of up to Mach
5."
Lots of people have websites with cool drawings of fast planes. I scanned the material on their site and didn't see anything concerning a flux capacitor, so my cynicism is slightly abated.
