WASHINGTON: Scientists have identified an extremely lightweight material that can withstand a high temperature and stress, a step towards developing hypersonic aircraft able to travel at five to 10 times the speed of sound. The study by researchers at NASA and Binghamton University in the US, could lead to a drastic decrease in flight times. The first of which is finding a material that can hold up to hypersonic travel. "Our study used what are called boron nitride nanotubes (BNNTs). However, researchers noted that carbon nanotubes were about the same price 20 years ago.
