Boeing hypersonic jet concept aims UK to US flight in 2 hrs
Aerospace company Boeing has unveiled its hypersonic jet concept which would be capable of flying from the UK to the US within 2 hours. The plane could theoretically fly as fast as Mach 5, or roughly 6,200 kmph. The Boeing company's CEO Dennis Muilenburg said that it might take a decade or more to see the jet "become a reality".
