How'd you like to see this outside your window?

Here's some of the debris. Another piece went through the roof of another house and into the kitchen.

Luckily, nobody was injured and the plane returned to the airport and landed safely.

In 2009, that's exactly what happened in my neighborhood (a bit outside my area I should say). I couldn't sleep, turned on CNN and there it was "Plane went down in flames, Clarence, NY". To say I was shocked, well, that's an understatement. I couldn't wrap my head around such carnage. Worse, I was working in Foster Care at the time. Many of those impacted were foster parents. Some had kids, some didn't. Most had severe issues looking out their windows at the wreckage. Shockingly, one person on the group lost his life. Of course all passengers were gone, but it could have been so much worse.
 
Pilots often practice with an engine failure while in a simulator. It's definitely an emergency situation. The pilot's main goal is then to get the plane back on the ground ASAP, just in case the second engine should blow. It's not all that uncommon to lose an engine during takeoffs while they (the engines) are putting out full thrust. Most of these planes can fly with just the one engine. The Boeing-777 is rated as one of the safest planes in the skies. I have flown in it and find it to be a very comfortable plane.

The Boeing-777 uses the Pratt and Whitney 4000 engine and puts out about 100,000 pound of thrust per engine. I always preferred the GE or my favorite engine still remains the Rolls Royce. If you listen closely, you can discriminate the difference between engines by their sound, especially the RR. It has a very high pitched sound, almost like a whistle. It's like music to my ears.
 
An uncle of my wife's did not come back from WWII. He was the navigator on a U.S. bomber. We ended up with many of the letters he wrote home while flying bombing missions over Germany. The letters tell how many bullet holes they counted in the plane after each bombing run. And... he was still confident the plane would fly. On one mission, a bullet came through the plane floor and took off a piece of his foot. He spent a week in a field hospital getting patched up. Back in the plane. Eight days before the Germans surrendered, they were returning from a bombing run in a dense fog. Hit a power line. The plane crashed and all on board were lost. My wife's mother always said she would never forget the screams from her mother... my wife's grandmother... when the telegram was delivered.
The ability for a plane in the 1940's to stay in the air full of bullet holes is a testament to aeronautical engineering clear back then. And... it has come so very far today. There are still tragedies. The Boeing 737 Max disasters. Plane crashes take so many lives in a single disaster. Yet, air transportation is so much safer than, even, automobile travel.
That a plane carrying over 200 souls can have one of its engines leave a trail of parts strewn over miles as it falls apart... and that plane still land with no injuries to those aboard... is an accolade to engineering technology. I hate heights... but love to fly!!!

Flying back during WWII was a challenge. Compared to today’s warplanes, it’s like day and night. Flying a plane full of bullet holes would not be considered as a good day of flying, however, if the plane safely landed, he would or should have been considered a hero.

The 737-MAX was a disaster created by Boeing. They added the MCAS to the flight systems, but never fully explained to any company that bought the plane how it was to be used. Using a larger, heavier engine was proportionally relocated on the wing in order to accept the larger engine. Thus, it was required to have a system to adjust the AoA, or Angle of Attack of the aircraft to keep the plane slightly nose up.

If the nose would dip, even so slightly, the MCAS would kick in and raise the nose. This action confused the untrained pilots. The MCAS was developed to automatically raise the nose, but the untrained pilots became confused and would also attempt to raise the nose mechanically, which in turn would cause the MCAS to fight against the pilot’s inputs. Boeing later admitted that the system should have shutdown, if the pilot made any adjustments to alter the AoA.

There hasn’t been a fatal air crash in the U.S. since 2009. A Colgan Airplane crashed in Buffalo killing all 49 onboard and one man in a house that was also struck. After I read the NTSB report, I agreed that the crash was mostly caused by pilot error. The male Captain had been placed into a remedial retraining program. The female F/O had flown on many legs during the day and is reported to have been fatigued. This is not a good combination to be in a cockpit.

When I would sit inside the plane and spool up the engine, the RR engine would whine as it powered up. When it reached full thrust, it sounded like a whistle. Release the brakes and down the runway we would go until we reached t/o speed.

There is no argument that GE sells more engines than the other two main engine manufacturers. P&W is second with RR bringing up the rear. However, most pilots will tell you that they prefer the RR engine, but costs rule when buying a plane. Competition is pretty fierce in the jet engine market.

I once read that the engines being used on the Triple Seven (B-777) puts out about 115,000 hp. and costs about $25,000,000.00 per engine. That’s a lot of everything for most of us.
 
Good to see you back, Oldman! I hope you are feeling much better.

Off topic, but I have a question for you --in aviation, when they are speaking of miles, like on speeds per hour and distances to airports, etc., are they talking about land miles or nautical miles?
 
Nautical miles only. This is what we use to do the math to figure our fuel load. In fact, us old-timers still do the math using a pen and paper, even though the onboard FMS will do it for the pilots. Some airlines also have the flight planner do the math. Having the right amount of fuel onboard, plus reserves is seriously important. The airline doesn’t like pilots doing a “fill ‘er up.” The more fuel onboard, the heavier the plane and the more fuel is used.

FMS = Flight Management System. This is the computer that sits between the Captain and the F/O. (F/O = First Officer)
