...point, Khan was worth some $400 million. With his clandestine income, Khan became a multimillionaire who collected vintage cars and foreign properties. Outside his mansion in Islamabad, he had a jasmine bush trimmed into the shape of a mushroom cloud...
Even though they fly in more challenging conditions, medical-helicopter pilots are not required by the FAA to be trained to fly using only their instruments. In any case, most helicopters lack the necessary technology. So when a helicopter pilot flies into a cloud and can't see out his windows, it is - by definition - an emergency. The pilot must simultaneously descend until he can see lights on the ground, toggle multiple radio frequencies to inform nearby planes and airports that he is flying blind, maintain control of a twitchy aircraft in conditions he is not trained to handle, over...
Wayne Kirby's last helicopter mission came on a warm and moonless night in South Texas on June 8, 2008. A few scattered clouds floated 1,200 ft. above the Huntsville International Airport. The sky was clear for miles. But just south of town, a low cloud swept in over Sam Houston National Forest. The fog already had thwarted another helicopter pilot who had tried to fly a patient from Huntsville Memorial Hospital to Houston. Blinded by the fog, that pilot was forced to turn around and abort the mission. Ninety minutes after that, Kirby was asked...
...knew about the first, failed mission. But he couldn't see the cloud, which lingered in a gap between airport weather stations. Kirby decided it was safe to launch. He flew his bright yellow Bell 407 helicopter to the hospital, picked up the patient, and took off for Houston at 2:46 a.m. Two minutes later, Kirby was flying 600 ft. above dense forest at 122 m.p.h., near the spot where the first pilot aborted. Kirby lost radio contact with the hospital in Houston. His helicopter dropped suddenly, to 100 ft. Its rotor sliced into thick pine trees. The cabin...
...silver lining of this massive brown cloud is that a boost in those technologies could decrease soot emissions - fast. "We can't fix every environmental problem, but we can make a huge and immediate change by reducing black carbon," says Veerabhadran Ramanathan, Director of the Center for Clouds, Chemistry & Climate at the University of California at San Diego. (Black carbon manifests as soot particles that comprise brown clouds.) While carbon dioxide levels in the atmosphere respond on a sluggish 100-year timescale to reductions in emissions, soot particles, whose effects are equivalent to roughly half the warming damage that carbon...
