Around 11:30 a.m. on June 30, 1956, a TWA Super Constellation and a United DC-7, together carrying 128 people, collided over the Grand Canyon at 21,000 feet. The collision ripped the tail off the Constellation and severed much of the DC-7’s left wing. The Constellation plunged in a near vertical dive and crashed about 300 feet above the Colorado River onto a relatively flat area called Temple Butte. The United DC-7 staggered about one mile north before it slammed just below the top of a formation named Chuar Butte and slid into a rugged gulch.

Do you have any idea what a degree in Philosophy in Physics involves? Neither do most people. But Thornton has a PhD in it, as well as bachelors and masters degrees in physics. So she’s scary smart, but she’s also scary tough. Part of the astronaut class of 1985, she flew four missions aboard three different shuttles and logged 975 hours aloft—21 of them spent outside the spacecraft conducting spacewalks. On her third mission, in 1993, she helpedcapture and repair the Hubble Space Telescope, marking that flight as one of the most scientifically consequential ones of the entire shuttle program.

“The Boz,” taken by the Seattle Seahawks with the first pick in the 1987 supplemental draft, had it all. Mohawk? Check. Bad acting chops in terrible movies (Stone Cold, One Tough Bastard)? Oh yeah. A signature on-field moment? Yes, sir: Monday Night Football, 1987, when Los Angeles Raiders running back Bo Jackson steamrolled over Bosworth on his way to the end zone. The only thing the University of Oklahoma linebacker was really missing?

On Tuesday, Toyota issued a “do not drive” advisory for 2003-2004 Corolla, 2003-2004 Corolla Matrix, and model year 2004-2005 RAV4 vehicles because of their use of Takata airbags that could explode and kill them. This comes after a much bigger recall was announced in December, impacting 1.12 million vehicles also involving vehicle air bags.  “If the airbag deploys, a part inside is more likely to explode and shoot sharp metal fragments which could cause SERIOUS INJURY or DEATH,” the Japanese automaker wrote in its announcement.
