Regular nonstop flights between the east coast of Australia and London or New York could soon become a reality.In preparation, Australian airline Qantas has announced three test flights, with 40 people traveling directly from London or New York to Sydney, to see how the human body copes with 19 solid hours of air travel.Qantas previously announced its goal of operating direct flights between London, New York, and three Australian cities -- Sydney, Brisbane and Melbourne -- by 2023.The test flights scheduled for October, November and December will move the airline closer to that target and enable Qantas, alongside medical experts, to test the health and wellbeing impacts on passengers and crew.Bjorn Fehrm, an aeronautical and economic analyst at Leeham News, explains to CNN the appeal of the ultra-long-haul flight, as opposed to a more typical two-part journey stopping in Dubai or Singapore.There's no layovers, no extra journeys through customs and no transfer stress, he points out. "You can plan it so you fly over night, and you could arrive to actually have a productive day the next day as well," says Fehrm. "It's going to be businesspeople that fly this way."If the 19-hour flight becomes a reality, it's likely to cost travelers more. "It's cheaper for the airline to do two separate flights," Fehrm says. "But some people are prepared to pay the extra price of that ticket."Before the trials begin later this year, three Boeing 787-9 Dreamliners, fresh off the production line, will be flown from Boeing's factory in Seattle to either London or New York.After the test flights -- two from New York, one from London -- the new planes will enter commercial service. Most of the people on board the test flights will be Qantas employees, so seats won't be available for purchase.Researchers from Sydney University's Charles Perkins Centre, Monash University and the Alertness Safety and Productivity Cooperative Research Centre -- a scientific program backed by the Australian government -- will examine the impact of the long flight on those on board.Passengers in the main cabin will wear monitoring devices, and experts from the Charles Perkins Centre will study how their "health, wellbeing and body clock" are impacted by a set of variables that include lighting, food and drink, movement, sleep patterns and inflight entertainment.Monash University scientists will focus on the flight crew, recording their melatonin levels before, during and after the flights, as well as studying brain wave data from electroencephalogram devices worn by the pilots.This information will then be shared with the Civil Aviation Safety Authority "to help inform regulatory requirements associated with ultra-long haul flights," Qantas said in a 2765

South Dakota doesn't get a lot of tornadoes, but a twister there last weekend was particularly rare -- because it was spinning clockwise.The National Weather Service says the anticyclonic tornado only lasted for about 45 seconds on June 15. That was long enough for it to knock down seven trees at a farmstead outside of Estelline, which is about 80 miles north of Sioux Falls.Only about 1% of tornadoes that hit the Northern Hemisphere rotate in a clockwise direction, the National Weather service says. The weather service used radar data and video to make its determination about the South Dakota storm.Becky Bates shot one of those videos while chasing the storm with her family."It honestly didn't seem unusual to me," Bates told CNN. "This was my first catch. I just chase for fun. But it touched down a couple of times while we sat and watched."The tornado had estimated peak winds of 75 mph and its path was about one tenth of a mile long.It caused only relatively minor damage. One of the downed trees bent the metal overhang on a shed.The-CNN-Wire? & ? 2019 Cable News Network, Inc., a Time Warner Company. All rights reserved. 1153
