In a world of increasing automation, the incident serves as a reminder of the importance of keeping a human backup in the loop.

In a world of increasing automation, the incident serves as a reminder of the importance of keeping a human backup in the loop.

That example also highlights the dangers of a common mode fault due to using the same singular one design team/system/spec...

Looks like the hardware and design worked exactly as designed.

However: The source problem was (is?) a flawed design of the operating laws that introduces a discontinuity in the rules/programming being used at the critical moment of touchdown for landing!

Would you be happy about a change of pilots whereby the flying pilot has to get out of his seat to let the ground driving pilot take over?...


For my designer's personal view and opinion: Relaxing the monitoring tolerances is a kludge fix that need to be looked at again for a more robust solution!

... At least that one is a one-in-a-million landings real-world (honestly unexpected systems) fail that the pilots were able to recover from.


Fly safe folks!

The Halo head and neck shield has saved the life of Lewis Hamilton when the car of Max Verstappen fell on Lewis's Mercedes. Many pilots were against this encumbrance but it proved useful.

Homeless man sleeping on tracks hit by train in West 7th area of Fort Worth, police say
The man, who was experiencing homelessness, was sleeping on the tracks when the train arrived and couldn’t stop, police said.

The man may have suffered a broken right leg, authorities said.

Man Sick Of Speed Bumps Chops Them Up With A Pickaxe — Then Gets Slapped With $500 City Fine
BRIGHTON PARK Neighborhood, Chicago IL— Annoyed with the speed bumps in his Brighton Park alley, (The man) took matters into his own hands.

For about three weeks, he’s been hacking away at the decades-old asphalt speed bumps outside his garage in the alley off the 4200 block of South Mozart Street. It’s tedious work, all after he gets off of work — one swing of a pickaxe at a time.

How could he miss seeing the truck in front of him?

Toyota Camry drives straight into stopped truck in peculiar dashcam footage.

Phone?
That gets my vote.


As happened yesterday afternoon to one of the blokes from work. He stopped at a roundabout to let the traffic already there go through, when he got hit from behind. Numb nuts was too busy with his phone to notice the car in front had stopped.

Having seen the youtube channel of Dashcam owners of Austrailia this is about average for the antics some are funny some are downright insane.

Footage captures car careering across eight lanes in Australia - BBC News
She saw that no one was in the Macca's drive thru and went for the break in the traffic to make sure that no one got in front of her. ;-)

Cheers.

Driver’s skeleton passenger gets him a ticket on the ‘Bony Express,’ Texas cops say

Those carpool lanes are meant for vehicles with two or more people, according to the Texas Department of Transportation. And as this driver learned, skeletons don’t count as a person.

If she is carrying TWINS it would count as three??? :-
... most native born Texas woman drivers are generally smarter than the men and would not try to press their luck with such gimmicks.

Wrong type of leaves on track could be a thing of the past.
Thanks to a technique which uses dry ice which freezes the leaves, making them brittle, developed by University of Sheffield engineers.

I hope they source their CO2 responsibly, and don't let it leak into the atmosphere - otherwise, they'll need even more cooling power to freeze the leaves next year.
