Re: Close attention pays off

KGround, there is a fundamental fatal flaw in the very concept of self driving cars not needing attentive and competent drivers, which is that those smart cars will never be able to handle all possible exceptions. Instead, they will do stupid and unsafe things, like stop in the fast lane at night, or swerve to miss a suitcase that falls into the road, and right into a slowwer moving truck. So a self driving car might make the poor driver a bit less agravating some of the time, and possibly safer much of the time, but NEVER both all of the time.

After watching a ton of Air Disasters episodes, it's not uncommon for the tiniest of issues to become full-fledged problems. Even a faulty indicator light has brought down aircraft, which is frightening.

In one of the newslettter reports I had been reading, the tank wall and aircraft skin were one and the same. The tank imploded in flight, changing the shape of the edge of the wing, and seriously affecting aerodynamics of the aircraft. An emergency landing was made and the pilot walked away from the event, perhaps with soiled pants, but otherwise unharmed. 

The cause was later found to be a blocked fuel vent.

Boat Will Not Turn Over

My Blue Water boat with Mercury 3.7 L engine would not turn over.  Further more I could not turn it over by hand.  Drained the fluids and took off the head, intake and exhaust.  The fourth cylinder the closest to the sea had the exhaust clogged with salt and the piston was frozen - stuck. I got a hydraulic ram and supported the bottom of the boat.  Still could not get it to move.

Getting the pan off was a real thrill also.  I lined the cylinder with newspaper and added dry ice and then tried the ram.  In between I also tried WD-40 and other penitrants - nogo.

Finally the piston moved.  Took the head in for rework and the machinist found cracks radiating around a couple of valve guides.  (he recognized a big Ford head - Mercury has their own foundry and builds engines for others) Got a new head and started reassembly.  Noticed a pin hole in the riser of the exhaust.  Got a new riser. Finished assembly.  Ran the engine in the driveway with water.  Ran good and strong up to full throttle.  Took the boat out to the lake and half way around it stumbled and quit.  Back on the kicker.

Disassembled engine again and hoping not for a valve clash.  Only a little smile on the piston and a stuck valve.  Took the head back to the machinist who cussed me out on sticking with such a poor design (steel head on aluminum block).  Hey I had $3K into it and the WIFE was not buying a new boat.  The guides were too tight.  I had understood from Mercury that the head was ready to install.  Guess you need to check on everyone.  Just think how big the V-8 was that two of those heads 7.4L?

It's a great saying, kenish, whoever came up with it.

I liked the saying too, but it was from another, earlier post.  I don't want to steal credit for it....

I like that saying, kenish. Sometimes, though, even the best of pilots can't overcome the emergency. When I was in college, I worked as a custodian for a building full of doctors' offices. The building was owned by a major airline captain with 30 years commercial experience, who eventually died while piloting his own private plane.

Yup, that's my girl.  Painted gold, my wife named her "Gold Digger", because she's taking all the money from a middle-aged man.

"Subsequent flight instructors both military and civilian, as well as German sailplane instructors all shared the opinion that any damned fool can fly a working airplane, however it takes a pilot to fly one in an emergency."

Reminds me of the Air Canada 767 that ran out of fuel:

and a very similar incident years later on Air Transat:

Random bad luck they were both Canadian airlines...not picking on our friends to the north :)

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
