Virgin Galactic will attempt one of its highest and fastest test flights ever on Wednesday, and it could bring the company closer to its goal of launching paying customers to space this year.A rocket-powered plane, called VSS Unity, is scheduled to lift off from the Mojave Air and Space Port in California Wednesday morning. Two veteran test pilots will be on board: Dave Mackay, the head of Virgin Galactic's pilot corps, and former Air Force lieutenant colonel Mike "Sooch" Masucci.Virgin Galactic 513

UNITED KINGDOM — It was a 7-hour delay for more than 300 passengers and crew on board a Pakistan International Airlines flight this weekend after a woman mistook an emergency exit door for the plane's restroom.Once she opened it, the airplane's emergency chute deployed. That spurred a series of events.The plane was still on the ground; it was about to push back from the gate. (Which begs the question: Why was the passenger out of her seat at the time?) An airplane's emergency door cannot be opened when an airplane is in-flight as the pressure won't allow it. Last month, a passenger on a Ryanair flight (also from the Manchester Airport) tried to open a door in-flight, and he was tackled by other passengers. The door would not have opened.A chute deploys at 3,000 pounds of air per square inch. If someone had been standing by the Pakistan International Airlines airplane where it opened, they could have been killed. In 2010 when a JetBlue flight attendant popped open a flight's emergency slide and went down it following a verbal altercation with a passenger, it was estimated it cost ,000 to replace the slide.Fortunately, no one was injured on the Manchester Airport ground when the woman on the PIA flight opened the emergency door. But the incident added seven hours onto the schedule for the airplane — which was already scheduled for a 7-hour, 50-minute flight to Islamabad. Here are some of the things the mistake spurred:? By aviation rules, the slide has to be removed and replaced. It can be used again once it is tested for safety? The crew had to re-seat or offload nearly 60 passengers — the rear door could no longer be used in an emergency? Offloaded passengers were given transportation to a hotel and hotel accommodations? The offloaded passengers were given the opportunity to take next available flightOfficials say some media outlets reported shortly after the incident that the plane was on the runway during the incident, but that is not correct.Deploying a passenger airplane chute is very costly: An average of million annually is lost in North America alone due to accidental slide deployments, 2155

While the winter solstice is still nine days away, you can take solace in knowing that the Sun is starting to set later in the evening for most of the northern hemisphere. For instance, the sunset for Thursday in New York City is 4:28 p.m. On Friday, it will be 4:29 p.m. By the time of the winter solstice, the sun will set on New York City at 4:32 p.m.Before you pop Champagne and begin welcoming summer, we are still days away from the shortest day of the year.Make sense yet? It turns out while our sunsets will begin to get later, and continue to do so until the end of June, sunrise times will also continue to be later through roughly Jan. 1. So for most Americans, the shortest day of the year is indeed Dec. 21, when the solstice actually happens.Why does this happen?It is because Earth's orbit around the Sun is not perfectly around, and sometimes we find ourselves a little closer to the Sun. The Earth is actually 3 million miles closer to the Sun in January than in July. This slight change is enough to change when the Sun sets and rises.Because of Earth's shifting distance from the sun, the time it takes for the sun to get to the same point in the sky gets later each day through the month of December. What is considered high-Noon sunlight also becomes later through the month. 1308

When finding food is you daily goal, there’s a simple saying to live by: use everything, waste nothing.That is We Don’t Waste’s game plan for ending food waste. Five days a week, the Denver-based non-profit group stocks up on food that will be thrown out, often times for pretty superficial reasons. “If it has dirt on it, if it has a little bruising: landfill,” says Arlan Prebld, executive director and founder of We Don’t Waste. Preblud started the non-profit a few years ago by recovering food rejected by restaurants and grocery stores and distributing it from the trunk of his car. Fast-forward to today, his team collects enough food to fill a massive distribution center in north Denver.“Last year, we put out 31 million servings,” Preblud says. “The collateral benefit of all that is all that food you see and that we deliver on a regular daily basis would end up in the landfill.” And a lot of food ends up in landfills across the country. According to the United States Department of Agriculture, 133 billion pounds and 1 billion worth of food were wasted in 2010. Preblud adds that impact goes well beyond the economy and into the environment. “When you put food into a landfill, it generates CO2 equivalence," he says. "Methane gas destroying the atmosphere."In addition to emitting greenhouse gases, wasted food also wastes the resources it took to produce, package, sell and transport it. So, in theory, by picking up what would be food by the pallet-full and trucking it to those in need, We Don’t Waste is filling many needs. “It’s great that we have partners that care about these people as much as we do, because, as you know, must people don’t,” says Doyle Robinson of Sox Place, a drop-in center for homeless youth in Denver. We Don’t Waste delivers food to Sox Place a few times a week. Doyle, however, says much the gesture provides much more than meals. “It’s great to find people that care and they do this because they care,” he says. “There’s no money in this." 2003
