I worked at a Large Internet Infrastructure Company for a long time, and saw software development practices that made my hair curl. All I could think was, "Gee, I'm glad we're not working on aviation software!" Seriously, though: software "engineering" could actually earn the name, if we had rigorous professional standards, regulatory oversight, and product liability.

There have been attempts (the "Keep the Space Shuttle Flying" method): https://github.com/kubernetes/kubernetes/blob/ec2e767e593953...

The PBS News Hour is pretty solid, https://www.youtube.com/user/PBSNewsHour The weekly videos from Robert Wright & Mickey Kaus on Bloggingheads Tv is pretty good too. https://www.youtube.com/channel/UCeamuoYuBeRnRRbmq5CmjVg

PBS news hour is a total of 6 hours per week (weekend shows are 30 minutes each). In those 6 hours, they cover more than any one of the 24 hour news networks. You're killing your mind watching 24 hour news networks, any of them.

Thanks, yeh I think when I want US News I might look at those instead

Almost identical incident happened 3 years ago - the same type (B777-200), the same engine (PW4077), the same operator (United Airlines), the same side (right engine), the same failure (unconfined engine failure).

I would not be surprised if the whole fleet of this type/engine gets grounded for some time.

You can hear the fire alert going off before the mayday. The fact that they requested a left turn at first it meant the controller knew the right engine was out and they'd need left turns to come in. Always find the level of training impressive and I'm glad they made it back safely. Aviate, Navigate, Communicate

I don't follow how the right engine being out means left turns. Seems like you'd have extra thrust on the left side and you'd want to make right turns. They wanted to keep the right engine high? I'm not sure what I missed.

Turning into the live engine is more controllable. When you turn toward the dead engine, the tendency is to turn more. You can do it, but it’s not as stable.

It’s designed to fly with only one engine. Not with great performance, but it will stay in the air. Routine procedure for twin engine aircraft.

Not only fly but climb. Commercial aircraft are required to fly safely should one of the two engines fail at any point of the flight, including takeoff at speeds beyond v1.

For the uninformed:

V1: Speed at which the take off attempt should no longer be aborted

Vr: Speed at which the plane should be pitched up (rotated)

V2: Speed at which the plane can safely climb with one engine

If an engine fails after V1 the runway is supposed to have sufficient length that you can hit Vr, rotate, and be 35 feet off the ground and traveling at V2 before you run out of tarmac even with a single engine.

And I’m supposed to fly on a 777-200 to Denver operated by United in just a few days. Yay!

I really appreciate focused news sites like avherald. Just the facts, a collection of photos and videos, straightforward. The video of the landing & the passengers cheering—- that huge sigh of relief. Brings a smile to my face.

What, you don’t like the anchor people on TV asking each other how they feel about every piece of news and making horrible puns at every opportunity? Or having expected announcements be reported as BREAKING NEWS?

Am I the only one who get really tired of this kind of sarcasm?

As a European who tuned in to US News for the US election I thought that was crazy. I'd watch a few of the right media orgs to see what they were saying and then stay on CNN/MSNBC etc for most of it. It's mad how so much of it every hour was essentially people just regurgitating stuff to fill the time. I mean OK what's happening is important but if you can't fill the airtime why not shift to other news (as in everyth…

I think the answer is don't watch TV news if you can help it. If 100% of their revenue comes from ads, then their incentives are clear: keep you watching no matter what. The way I see it, written news at least has a wider range of options, and the subscription model means they have slightly less incentive to be so manipulative.

Yep agree absolutely. I probably read 5-10 different global media a day normally online. I rarely watch TV news but it was sort of an experiment I guess. Wow some of the stuff on places like Newsmax made Fox look like The Guardian.

The same point could be made without sarcasm. Would you object, then?
