Air Force's X-51 Scramjet Sets Record for Longest Hypersonic Flight
By Tariq Malik

An experimental aircraft has set a new record for the longest hypersonic flight after streaking across the sky Wednesday for more than three minutes while flying at Mach 5 – five times the speed of sound — the United States Air Force has announced.
The vehicle, called the X-51A Waverider, dropped from a B-52 Stratofortress mother ship while flying over the Pacific Ocean just off the southern California coast. It successfully ignited an air-breathing scramjet engine than accelerated up to Mach 5, Air Force officials said in the announcement.

THE GIST:
  • For the first time, scientists have successfully extracted DNA from fossilized eggshells.
  • Since many of the eggshells belonged to extinct birds, it may now be possible to learn more about mysterious prehistoric species.
  • Eggs retrieved from cold climates could lead to recovery of very ancient DNA.
