Boeing's 787 was only grounded for a couple of months and looks like it will fly again by the end of this month. Bad, but read this.
Eurocopter EC225's (a big helicopter used to support North Sea oil drilling) was grounded in October of 2012 and looks to stay grounded until this fall. Grounding was ordered by both the British and the Norwegian governments after two forced landings in the North Sea, caused by failures in the main gear box. The main gearbox connects the engines to the rotor. When that breaks the rotor stops turning and the chopper falls out of the sky.
That's a lot worse than flaming lithium batteries.

Airline money sink, GEN-X
GEN-X is the FAA scheme to modernize the entire US air traffic control system. Today's system works on ground radar stations, straight out of World War II. Controller eyeball the radar screens and radio flight orders to airliners to keep them from colliding. The radar beams are fairly tight, 3 degrees, but that means an uncertainty of plus or minus 2.5 miles when the plane is 100 miles from the radar station. So controllers maintain a ten mile spacing between planes.
GEN-X requires all aircraft to carry a GPS and a special transmitter to send the aircraft's GPS position to the ground station. GPS is accurate to 100 feet and so the planes can be packed up tighter in the sky.
The GEN-X equipment costs $500,000 per airliner. Right now the airlines are supposed to pay for this, although FAA will make loans to airlines to fund GEN-X installation. And, the airline gets no return on investment. With or without the $500,000 GEN-X equipment, the plane gets from here to there at the same speed. All GEN-X does for the airline is cost money. It doesn't offer any benefits.
The greater accuracy of GEN-X doesn't matter. Packing airplanes more tightly together in the sky won't help move more traffic. There is plenty of sky to hold all the airplanes. The bottleneck is airport runways. An airport can only handle one flight a minute, and all the major airports have been running at capacity for twenty years or more. I picnicked on Castle Island, just off Logan Airport, and watched a never ending stream of airliners, packed up head to tail, coming in for a landing. That was 20 years ago on a nice sunny day. It gets worse when the weather gets bad.
Any how, FAA is pushing hard for GEN-X, for mysterious reasons. Our tax money at work.

So what do you do with an International Space Station?
Now that we have one. Serious money was put into it. Now it is up there with not much to do. The earth imaging mission is handled by recon satellites good enough to spot a cigarette pack lying on the ground. The astronomy mission is well in hand at Hubble. They aren't enough tourists with money to make an orbital tourist hotel work.
According to Aviation Week, they have space to spare for more scientists and experiments. The only work on going is "micro gravity" (we used to call it weightlessness) what ever that means. Could it be that the best part of ISS was the "International" part of the name. That helped mightily at funding time.

Quibble
The surviving Boston bomber has been charged with "using a weapon of mass destruction". "Weapons of mass destruction" is diplo-speak for nukes. Diplomats have trouble with the English language.
The Boston bombs weren't nukes.
How about a charge of plain old murder in the first degree? Four counts. Murder is murder whether it is done with bare hands, firearms, bombs, or anything. Killing is the crime, not the weapon used.

Furlough bureaucrats, not air traffic controllers
FAA surely has a bunch of bureaucrats that could be furloughed to save money. Instead FAA decided to furlough air traffic controllers to slow air travel and inflict as much pain on the public as possible. We would never miss bureaucrats. Air traffic controllers actually provide a needed service.

Common Core Curriculum
There is a national movement to create a nation school curriculum, the same in all states. It is controversial, lotta folks think the school curriculum in their state is nobody else's business. Lot of education folks like the idea of a national standard, to which they can point, when parents press them to soften up school standards.
The common core is posted on the web and Google led me to it. I scanned the math standards for first grade thru high school. They aren't very rigorous. And the have a lot of new age time wasters. For instance they try to introduce algebraic concepts in first grade. High school geometry proves some of the easier theorems but does NOT bother to prove the Pythagoras theorem. They don't understand the purpose of high school science labs.
In short, Common Core isn't going to improve anything. On the other hand it doesn't look like it does much damage.

French Govt buys from and owns the French defense industry
Long article about this in Aviation Week. The French government owns sizable chunks of stock in the big French defense firms like Dassault, Thales, and Sagam. Which puts the French in a confusing spot when they are negotiating contracts with the industry. There is pressure on the government to sign contracts generous to the contractors because the extra money will make the government's stock holdings worth more. Which does French tax payers no good at all.
Apparently the French government fears their companies will merge with companies in Germany and Britain, which will make it hard for the French to build up a French built armed force to fight a war with Germany or Britain. So the French use their stock holdings to put a veto on international mergers.
Aviation Week, an industry organ, is all in favor of defense industry mergers, it gives the merged company more pricing power. As in when we merge with all the competitors, we can charge as much as we like, 'cause there is nowhere else to go.
Fortunately the US government doesn't own stock in defense contractors.
