Front Landing Gear Grinds Off - Everyone Safe

World record- Longest tire skid?

This is off the topic but not completely unrelated. I used to own an old, rusty VW Golf. One day it literally broke in two and was held by the front-back differential rod in the middle. (I never figured why a differential rod is needed in a FWD but was glad there was one.) Obliviously I kept driving it for a few more weeks. In curves, the back half actually swayed in the opposite direction of the front.

Not a good idea, arresting gear landings slam the front wheel into the deck HARD! That would have caused real trouble in this situation. Watch the video, you will see that the pilot kept the front wheel off the runway as long as possible, then he let it down slow. Had it hit hard at full speed it may have folded, that would have been bad news.

This is not the only landing gear problem they could have now is it? I think it is a very good idea to have arresting gear as an option. There could be times when that would be the best option even if this time it was not...

Arresting gear is not suitable for a commercial aircraft. Structurally the aircraft is not designed to have an an arresting hook attached and then to absorb the subsequent stress on the airframe.

The operating procedures in use are quite safe today with reverse thrust, powerful brakes, some runways have breakable cement after the end of the runway to slow the aircraft if necessary. Pilot discretion and performance charts are also adequate in effecting the methods for stopping today.

Why not?

What kind of airframe do they have? There isn't a keel or a hefty longeron they could attach the arresting hook to?

It is not a matter of the actual attachment, but rather having the structure capable of sustaining a tremendous amount of force, starting at where the hook is connected to the aircraft. Also this would likely require a stronger nose wheel to absorb much of the force that will also be seen there as well.

This isn't something than can be modified to an airframe. Boeing, Airbus or whoever would have to build an entirely new design to incorporate this idea. I am sure it has been explored, but it just isn't worth it/necessary.

I don't see the problem at all...the arrested landing would be a one time only deal. It would be something to be used in emergencies where the other options lead to a greater risk of death and personal injury.

I think sean's point is that if the frame isn't rebuilt more strongly then the gear may not work at all.

P.S. By the same logic, each airplane can be equipped with an iron achor that will be thrown out of the exit door while the other end will be tightly held by the crew. Much less expensive, yet it could work as good as any other bandaid solution.

Another excelent European product saves the day :-) *hopes the axel was made in the EU*

I've never heard of a landing gear screw up where stopping the plane was the issue.
