The biggest thing holding us back right now is cost and economy. From the 70s right up until 2003 you could fly from the UK to New York in 3 hours. But the economy killed Concorde and nobody has even tried to build a supersonic passenger aircraft since. Today's airliners are cheap, fuel-efficient and carry as many passengers as possible to make the most money.
