Great little video, produced entirely using desktop computers, about a DC-10 (or is at an MD-11) making an emergency landing on I-405 in LA.  

Visit
http://www.pcworld.com/downloads/file_description.asp?fid=7979,

for a brief write-up on the movie.

Is it really possible for an airliner of this size to make an emergency landing on a freeway?  (I think the whole SUV being the nosewheel is, of course, quite far-fetched).

DC10 lol
is it possible, possibly but the road would need to be perfectly straight with no lamp posts on either side. dont know what the weight of the plane would do to the surface though

I wonder how the road would react to such extremely overload  ???  Smiley
I mean a DC10 would not really kiss the asphalt during an emergency ladning  Grin

Well taking the bearing strength of the road surface, divided by the modulus, add in the max. weight on each tire at touchdown along with a few more variables adn I'm sure you can figure it out..

typically a runway can be around 35 inches in the runway touchdown zone, and is typically around 6-8 inches in non-critical areas such as the middle of the runway where it will not have to abosrb as much force...

The runways we have over here are everything from 60 to 120 cm thick (concrete and asphalt layers), I was never good with inches  Grin

But consider the average road is what, 2dm thick, and it's just asphalt above a gravel bed (at least in Sweden, we don't have the concrete highways)  Smiley
A few bumps here and there is not impossible  Grin

It probably is not possible, the forces from a DC-10 landing would probably crush right through the highway since it is probably only 8-10" thick. BTW I don't think any SUV could stand the force of a DC-10 nose falling on it Grin

You say that but in a number of countries main roads are designed for emergency landings. And frankly the German Autobahns being concrete probably could take it, they could handle me trying to tear them up in a number of vehicles Shocked Grin 8)

Well I've never seen a sign on a motorway bridge saying no flying underneath, mind you my German is pretty poor Grin Grin Grin

a few remarks:

- new runways are designed to be able to withstand 600tons of weight. it depends on the road, but normally those aren't calculated for this weight.

- in Japan (or was it China) they practiced a few months ago with take off's and landing on the highways. they did this with Mirage2000's. just in case their enemy destroys their military bases, they could still take off.  Roll Eyes

- i think this is posted before...wasn't Bman reply to this: "hey, that's filmed a few miles from where i live!"  Cheesy

ah but theres a differance between a 20 ton mirage and a 170 ton DC10, can you guess what it is Grin LOL

There isn't that much difference, just with a DC-10 you need a bridge with a bigger span Grin Grin Grin

Thsi is quite common. There are well known pictures of the Sepecat Jaguar operating off autobahns in the 70s and 80s. The Swedes also regularly did this with SAAB Viggens...

Also the A46 in Lincolnshire runs parallel to the old main runway at RAF Swinderby. There are several tales off WW2 heavy bombers trying to land on the road...

Not to burst any bubbles ...............but the greatest density emphasis is required at the gate, not the runway.  An airplane making a tight, low speed turn, creates a more tightly focused  downforce than one that is landing. On the same token, what do you think is the biggest cause of damage to aircraft interior floors, fat guys in loafers or 100lb women in 3" heels? (hint)Most people are surprised by the answer! The same general physics applies to the gate vs runway scenario.
 

.....so I loaded up the plane and moved to Middle-EEEE..........OIL..that is......
