I may be mis-remembering, but it seems like a summer or 2 ago, there was a day with 2 leap seconds in it.
Not possible. The leap second committee folks have a mandate never to let the difference between the UTC and UT1 (mean solar time) readings exceed 0.9 seconds. They usually decide to apply a leap second whenever the difference between UTC and UT1 approaches 0.6 seconds. Furthermore, they can add a leap second at the end of any month, although there is a preference for June and December and a second preference for March and September. For there to be two leap seconds in a day, something catastrophic would have had to have happened, like California sliding into the ocean, the Yosemite supervolcano blowing, or the Maple Leafs winning the Stanley Cup.
There's a big difference between knowing something is possible, and actually doing it.
In 1848, Sir George Cayley built a glider that carried a child, years before the Wright brothers were even born.
In 1856, Frenchman Jean-Marie Le Bris made the first flight higher than his point of departure, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. He reportedly achieved a height of 100 meters, over a distance of 200 meters.
In 1877, Enrico Forlanini developed an unmanned helicopter powered by a steam engine. It rose to a height of 13 meters, where it remained for some 20 seconds, after a vertical take-off in Milan.
in 1894, Sir Hiram Maxim constructed a large test rig to investigate aerodynamic lift. It's twin propellers were powered by two lightweight compound steam engines and it took three people to operate. It didn't have any flight controls so it ran on rails, with a second set of rails above the wheels to restrain it. On its third run it broke from the rail, became airborne for several hundred feet at two to three feet altitude.
On 14 August 1901, Gustave Whitehead carried out a controlled, powered flight in his Number 21 monoplane at Fairfield, Connecticut.
Wilbur and Orville Wright... Last inventors of the airplane.
That's what you think.
When ITER ignites a plasma early next decade, people will be completely blindsided.
Don't worry. The US will have ground troops go in long before that happens.
looks a bit like Han Solo's Millennium Falcon, towed in for repairs after a run-in with the Imperial fleet.
Sure, in the same way a croissant does.
Meaning, not at all.
Indeed! In every encounter I've seen between the Millennium Falcon and Imperial ships, whether it's dodging TIE fighters in an asteroid belt, playing tag with Imperial Star Destroyers, or tackling a Death Star, it's the Imperial ships that wind up being turned into scrap metal.
...shuttles' wasteful irresponsible uselessness, and total failure to achieve almost all of intended goals. everything they did do could have been done more efficiently in other ways.
It was still the most amazing and capable spacecraft ever developed.
