    Ex wife One evening, after the honeymoon, Tom was working on his Harley motorcycle in the garage. His new wife was standing there by the bench watching him. After a long period of silence she finally said: "Honey, I've just been thinking, now that we’re married, maybe it's time you quit spending so much of your time out here in your garage. You probably should consider selling your Harley and all that welding equipment; they take up so much of your time. And that gun collection and fishing gear, they just take up so much space. And you know the boat is such an ongoing expense; and you hardly use it. I also think you should lose all those stupid model airplanes and your home brewing equipment. And what’s the use of that vintage hot rod sports car?" Tom got a horrified look on his face. She noticed and said, "Darling, what's wrong?" He replied, "Just for a minute there, you were starting to sound like my ex-wife." "Ex-wife!?" she shouted, "YOU NEVER TOLD ME YOU WERE MARRIED BEFORE!" Tom replied, “I wasn't."

    Unprecedented images of supersonic shock waves NASA has captured the first-ever photos showing the shock-waves of supersonic jets interacting in flight. 2019 NASA captures unprecedented images of supersonic shock waves with help of 'rock star' pilots NASA has captured unprecedented photos of the interaction of shock waves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous “sonic booms.” When an aircraft crosses that threshold — around 1,225 kph (760 mph) at sea level — it produces waves from the pressure it puts on the air around it, which merge to cause the ear-splitting sound. In an intricate manoeuvre by “rock star” pilots at NASA’s Armstrong Flight Research Centre in California, two supersonic T-38 jets flew just 30 feet (nine meters) apart below another plane waiting to photograph them with an advanced, high-speed camera, the agency said. The rendezvous — at an altitude of around 30,000 feet — yielded mesmerizing images of the shock waves emanating from both planes. With one jet flying just behind the other, “the shocks are going to be shaped differently,” said Neal Smith of Aerospace Computing Inc., an engineering firm that works with NASA, in a post on the agency’s website. “This data is really going to help us advance our understanding of how these shocks interact.” Sonic booms can be a major nuisance, capable of not just startling people on the ground but also causing damage — like shattered windows — and this has led to strong restrictions on supersonic flight over land in jurisdictions like the United States. The ability to capture such detailed images of shock waves will be “crucial” to NASA’s development of the X-59, the agency said, an experimental supersonic plane it hopes will be able to break the sound barrier with just a rumble instead of a sonic boom. A breakthrough like that could lead to the loosening of flight restrictions and the return of commercial supersonic planes for the first time since Concorde was retired in 2003. Some countries and cities banned the Franco-British airliner from their airspace because of its sonic booms.
