![]() At the time of the Challenger accident it was in temporary storage in the Vehicle Assembly Building (VAB) at KSC. The orbiter had completed six missions, the last one, STS-51I, in August 1985. In 1986, NASA decided to use space shuttle Discovery for the return to flight mission. ![]() Right: A qualification test of the redesigned Solid Rocket Booster.

The agency augmented its safety culture and management structure to improve future decision making. To recover from the accident, NASA implemented over 200 changes to the Shuttle system, including redesign of the SRB field joints, addition of a crew escape pole to permit bailout from the vehicle under certain flight conditions, and having the crews wear full pressure Launch and Entry Suits (LES) during liftoff and landing. In addition to the hardware failure, the commission also identified cultural and management practices at NASA that led to the ill-fated decision to launch Challenger under those conditions, overriding technical analysis that it was not safe to do so. And when the O-rings failed, hot gases escaping from the SRB impinged on the External Tank’s liquid hydrogen tank, causing the fatal explosion. The commission determined the proximate cause of the accident to be O-rings in the field joints of the Solid Rocket Booster (SRB) that became brittle when exposed to cold temperatures such as on the day of Challenger’s launch.

The Return To Flight mission ended with a touchdown at Edwards Air Force Base in California. “Pinky” Nelson completed a four-day mission, deploying their primary payload, a Tracking and Data Relay Satellite, and conducting science and technology experiments. ![]() Discovery’s five-man crew of Frederick “Rick” H. The agency spent two years correcting the problems. A Presidential Commission investigating the accident identified proximate hardware and NASA organizational causes. The STS-26 mission returned American astronauts to space after a 32-month hiatus following the January 1986 Challenger accident that took the lives of seven astronauts. 29, 1988, space shuttle Discovery roared off its launch pad at NASA’s Kennedy Space Center (KSC) in Florida. We’ve bolded the wait times for the two Pandora attractions below so you can see when it makes the most sense to ride them.On Sept. Remember, this ride also offers an Individual Lightning Lane but keep checking the wait times on the My Disney Experience app throughout the day if you don’t want to pay to skip the line. The best time to get in line for these two rides can depend, but if you can wait until the last few hours that the park is open, that may be your best bet. However, Na’vi River Journey passed Flight of Passage for the highest wait time many times throughout the day. We’ve covered how stressful rope dropping this attraction can be. Flight of Passageīased on the wait times from Tuesday, October 3rd, the worst time to ride Flight of Passage may be in the morning hours. Yes, other parks have rides with long wait times (we’re looking at you, Slinky Dog Dash), but Flight of Passage continues to post the highest average wait time in all of Disney World each week. And that’s what we’re here to talk about today! However, the most popular parts of the land are the attractions - Flight of Passage and Na’vi River Journey. Not only is it gorgeous at night, but you can grab some of the iconic cheeseburger pods at Satu’li Canteen or the controversial Pongu Lumpia snack. Pandora was a huge addition to Animal Kingdom and it has quickly become the park’s most popular land! Animal Kingdom This Is the Hardest Ride to Get on in Disney World.
