Technology When supersonic is too slow, go hypersonic
Odell Beckham absent from Eli’s WR workouts
We don’t know where Odell Beckham Jr. is going to end up. But for now, he’s on the New York Giants. And every year, Eli Manning likes to hold a workout for his wide receivers. “As for Beckham, his absence wasn’t a surprise. He skipped the Manning/Duke camp last year too, saying he had previously scheduled oral surgery for the same week. He hasn’t spoken publicly since the end of last season, though, so his reasons for skipping this year’s session weren’t clear.
Still in development, the SABRE engine would breathe air at lower altitudes for a top speed of around Mach 5 (generally, hypersonic flight is at least five times the speed of sound), but then switch to a Mach 25 rocket mode when it reaches thinner altitudes at the edge of space.
And since then, no supersonic aircraft has been allowed to fly over land in the U.S. due to the sonic booms they produce. As for hypersonic travel, the last time a plane went hypersonic was in 1967 when Congressman Steve Knight’s father, the late William J. “Pete” Knight, piloted the North
© Provided by CNET reaction-engines Since the last flight of the Concorde 15 years ago, plenty of aerospace companies have been trying to keep the dream of faster-than-sound flight alive in one way or another.
One of those firms, UK-based Reaction Engines, got a boost Thursday when Boeing, Rolls-Royce and BAE Systems invested £26.5 million (about $37.4 million) in its hybrid aircraft engine that would operate both as a super-fast jet and a space-bound rocket.

Trump blasts the FBI and DOJ for 'slow walking' their response to a Republican subpoena
Mark Wilson/Getty Images President Donald Trump launched another salvo at the Department of Justice and the FBI Saturday, after the DOJ missed a deadline to respond to a document subpoena from Republicans on the House Judiciary Committee. Trump accused the DOJ of "slow walking" its response to the subpoena and suggested the agency had something to hide.Trump's broadsides against the DOJ and FBI have grown steadily louder as the Russia investigation closes in on the White House.

Set for ground testing by 2020, SABRE (it stands for Synergetic Air-Breathing Rocket Engine) could be used in several ways, including powering hypersonic passenger airliners and reusable space vehicles and launching satellites into orbit.
In its press release, Boeing's investment arm, HorizonX, didn't state how it might use SABRE, except that it expects "to leverage the revolutionary technology to support Boeing's pursuit of hypersonic flight." Rolls-Royce, which makes conventional subsonic jet engines in addition to cars, was equally cagey, saying it plans "to incorporate this technology into future products."
Black woman golfer: It was like we had targets on our backs .
One of five black women golfers who say they were told to leave a Pennsylvania club says it felt like they were "playing with targets on our backs." Sandra Harrison says representatives of the Grandview Golf Club told the group at the second hole they were playing too slowly. After the ninth hole, an hour and a half later, she says they were told they took too long a break and needed to leave. She says she and two other women left because they were so rattled by the treatment.The club called police on the two women who remained. No charges were filed.Club co-owner JJ Chronister has said she called the women personally to "sincerely apologize.
