I'm not a pilot, but I follow general aviation and am a bit of a nerd about it.

For like-minded souls, if there are any, I thought it might be fun to have a place to share stories, videos, etc.

I'll start with this one about a B-52 in a crosswind landing. Crosswind landings can be pretty hairy (for those who are unfamiliar with the term, a crosswind landing happens any time there is a wind blowing in a direction other than parallel with the runway, so they are pretty common) and this one is just cool because of the landing gear design of the B-52.

Enjoy...

So you are on a commercial flight, both pilots are suddenly incapacitated mid-flight and nobody is willing to act.

What would you do?
Depending on the aircraft and the carrier, the plane may be capable of landing itself.

Realistically, there's no way you are going to get into that cockpit if both pilots are out of commission: the post-9/11 security precautions isolate the cockpit from the cabin with a locked security door.

Auto-landing is still experimental AFAIK.

I've read that with most of airline companies, there are at least three people who can open the cockpit door, the pilots and crew chief.

Yes, indeed. There's an old adage that being a commercial pilot is "three hours of boredom followed by 90 seconds of sheer terror." :D

It reminds me about the Aisiana Flight 214, after spending half day in the air during an uneventful transocean flight, the aircraft's tail struck the airport barrier and crashed right on the runway.

How to Fly a Helicopter, by Dave Barry

:)

TODAY'S AVIATION TOPIC IS: How to fly a helicopter.

Although flying a helicopter may seem very difficult, the truth is that if you can drive a car, you can, with just a few minutes of instruction, take the controls of one of these amazing machines. Of course you would immediately crash and die. This is why you need to remember:

RULE ONE OF HELICOPTER PILOTING: Always have somebody sitting right next to you who actually knows how to fly the helicopter and can snatch the controls away from you. Because the truth is that helicopters are nothing at all like cars. Cars work because of basic scientific principles that everybody understands, such as internal combustion and parallel parking. Whereas scientists still have no idea what holds helicopters up. "Whatever it is, it could stop at any moment," is their current feeling. This leads us to:

RULE TWO OF HELICOPTER PILOTING: Maybe you should forget the entire thing.

This was what I was thinking on a recent Saturday morning as I stood outside a small airport in South Florida, where I was about to take my first helicopter lesson. This was not my idea. This was the idea of Pam Gallina-Raissiguier, a pilot who flies radio reporters over Miami during rush hour so they can alert drivers to traffic problems ("Bob, we have a three-mile backup on the interstate due to an overturned cocaine truck").

Pam is active in an international organization of women helicopter pilots called - Gloria Steinem, avert your eyes - the "Whirly Girls." She thought it would be a great idea for me to take a helicopter lesson.

I began having severe doubts when I saw Pam's helicopter. This was a small helicopter. It looked like it should have a little slot where you insert quarters to make it go up and down. I knew that if we got airborne in a helicopter this size in South Florida, some of our larger tropical flying insects could very well attempt to mate with us.

Also, this helicopter had no doors. As a Frequent Flyer, I know for a fact that all your leading U.S. airlines, despite being bankrupt, maintain a strict safety policy of having doors on their aircraft.

"Don't we need a larger helicopter?" I asked Pam. "With doors?"

"Get in," said Pam.

You don't defy a direct order from a Whirly Girl.

Now we're in the helicopter, and Pam is explaining the controls to me over the headset, but there's static and the engine is making a lot of noise.

". . . your throttle (something)," she is saying. "this is your cyclic and (something) your collective."

"What?" I say.

"(something) give you the controls when we reach 500 feet," Pam says.

"WHAT?" I say.

But Pam is not listening. She is moving a control thing and WHOOAAA we are off the ground, hovering, and now WHOOOOAAAAAA we are shooting up in the air, and there are still no doors on this particular helicopter.

Now Pam is giving me the main control thing.

RULE THREE OF HELICOPTER PILOTING: If anybody tries to give you the main control thing, refuse to take it.

Pam says: "You don't need hardly any pressure to . . ."

AIEEEEEEEEEEEEEE

"That was too much pressure," Pam says.

Now I am flying the helicopter. I AM FLYING THE HELICOPTER. I am flying it by not moving a single body part, for fear of jiggling the control thing. I look like the Lincoln Memorial statue of Abraham Lincoln, only more rigid.

"Make a right turn," Pam is saying.

I gingerly move the control thing one zillionth of an inch to the right and the helicopter LEANS OVER TOWARD MY SIDE AND THERE IS STILL NO DOOR HERE. I instantly move the thing one zillionth of an inch back.

"I'm not turning right," I inform Pam.

"What?" she says.

"Only left turns," I tell her. When you've been flying helicopters as long as I have, you know your limits.

After a while, it becomes clear to Pam that if she continues to allow the Lincoln statue to pilot the helicopter, we are going to wind up flying in a straight line until we run out of fuel, possibly over Antarctica so she takes the control thing back. That is the good news. The bad news is, she's now saying something about demonstrating an "emergency procedure."

"It's for when your engine dies," Pam says. "It's called "auto-rotation.' Do you like amusement park rides?"

I say: "No, I DOOOOOOOOOOOOO . . ."

RULE FOUR OF HELICOPTER PILOTING: "Auto-rotation" means "coming down out of the sky at about the same speed and aerodynamic stability as that of a forklift dropped from a bomber."

Now we're close to the ground (although my stomach is still at 500 feet), and Pam is completing my training by having me hover the helicopter.

RULE FIVE OF HELICOPTER PILOTING: You can't hover the helicopter.

The idea is to hang over one spot on the ground. I am hovering over an area approximately the size of Australia. I am swooping around sideways and backward like a crazed bumblebee. If I were trying to rescue a person from the roof of a 100-story burning building, the person would realize that it would be safer to simply jump. At times I think I am hovering upside-down. Even Pam looks nervous.

So I am very happy when we finally get back on the ground.

Pam tells me I did great, and she'd be glad to take me up again. I tell her that sounds like a fun idea.

RULE SIX OF HELICOPTER PILOTING: Sometimes you have to lie.

I'm guessing most of you have heard about the recent incident involving United 328's engine failure in a 777 shortly after takeoff from Denver International Airport. Very dramatic pictures and video and given the litter of pieces on the ground in Broomfield, Colorado, it's amazing no one was injured or killed.

A friend of mine sent me this twitter thread from a pilot, which offers some insight from a professional standpoint.
https://twitter.com/miami_rick/status/1363959675604004866

On a personal note, I have a friend who is a United pilot and when he was in the triple 7 several years back, he was flying some Pacific rim routes regularly. They lost an engine on one of those runs and were more than an hour away from the nearest land when it happened. They had another pilot deadheading in the jump seat with them, and after they descended and configured the plane for single-engine operation and the shortest route to an available airport, he said they all three had their eyes glued on every instrument pertaining to the remaining engine. ;) No surprise there!

The scariest thing about this to me is not that an engine failed, but that it was an uncontained failure. Commercial aviation jet engines are supposed to be designed so that if they fail, shrapnel doesn't go flying all over as that has the significant potential to damage the airplane and injure passengers (remember the poor lady who died after an uncontained engine failure in a 737NG a few years ago). The pic below shows significant damage to the lower fuselage of United 328, and it's just dumb luck or the grace of God that piece didn't penetrate elsewhere, which could potentially have resulted in injury or death to the passengers, or even the loss of the aircraft and catastrophic loss of life.

There are lots of pics and videos out there, but I'm only sharing this other one because it shows the fan failure (obviously this was taken after landing safely back at DIA). The Pratt Whitney engine uses "hollow" fan blades and that is very evident in this picture. What seems likely at this point is that the one blade broke close to the hub due to metal fatigue and damaged the blade next to it. These blades are about four feet in length; the whole engine inlet is itself larger than 9' in diameter.

Resurrecting this thread to note that I will soon be flying to Europe. I’m vaxxed and only a little concerned, since I’ll mask up for the flights as well.

On a personal note, I’m excited to fly on the 787 Dreamliner (one direction United, the other Lufthansa). That it has excellent air filtration is another bonus. ;)

To get to the Dreamliner, the first hop is to ORD on United as well, and a friend (who is a UAL captain) has bid on the flight. I’m really hoping he gets it, I haven’t seen him in such a long while and I’ve never flown with him. Of course in these post-Bin Laden days there wouldn’t be any cockpit visit or anything like that anyway, but it would still be pretty cool. ;)
