News Icelandic volcano eruption threatens flights across Europe

I don't care how you look. I say that you have not even basic knowledge about engine operations. How your look relates to what you have inside your brain or your skills, is not at all understandable to me, maybe you want to explain it to me.

I think he was being ironic... i.e. saying that he doesn't know much about planes.

 

[garyw]

Look.
Part of my claim is correct, as a plane blows it out to push it to gain thrust to have airflow under the wings.

If it just sucks, then we would be on a planet with no atmosphere.

This isn't the thread to discuss how planes work. There are already plenty of other sites that can deal with this. I would suggest that you start with Bernoulli's principle

*argh*

Homework for you:

1. Look for the definition of thrust.
2. Look for the position of the exhaust nozzles of a jetliner relative to the wings. Or the location of a planes propeller relative to the wings.
3. Look for the definition of aerodynamic lift and Bernoulli's law. Explain on which side of the wing the faster airflow has to be.
4. Look for the definition of "correct".
5. Give cjp 500 Euro, since I just found out that there is no continental drift between Germany and Netherlands.

Since planes don't fly, continental drift. :lol:

Since you don't deny, and thereby implicitly agree, having a debt of 500 Euro to me, I think a short trip to Wolfsburg could be profitable to me! :thumbup:

If you want to organize a European Orbinaut meeting, you could offer 500 Euro to all who can answer the question correctly. We can then have a continental drifting party.

:lol: You still need to locate me then.

And get back home...

In this case it would be a Orbinaut 500 Euro question... not such easy questions for groundhogs.

Here is live webcam feed from the Iceland volcano. Although it`s cloudy you can sometimes make out eruption plume between the clouds.

Looks like the volcano is still going strong.

Yeah, I've seen some horrific pictures and videos too... No wonder so many flights have been cancelled. Some forecasts predict that this situation may continue for another several weeks!!! Let's hope they're wrong...

The problem is, that there seems to be less ash above Europe as predicted by the computer simulations, that are used for justifying the ban. Its a bad situation. If they are permitted to fly, and a plane crashes, it is as bad as having air traffic in europe grounded.

I'd dare say it's worse. Better be on the safe side with this...

I do appreciate the efforts by airlines to test the conditions, though. I Was rather impressed that the big shot of british airways went up himself.

Dunkirk revisited:

Three Royal Navy ships are on their way to help repatriate up to 200,000 Britons stranded by five days of flight restrictions following the Icelandic volcano eruption.
The aircraft carrier Ark Royal and the assault ships Ocean and Albion were today deployed to help increase cross-Channel options as the no-flight ban across Britain was extended until 1am tomorrow.


Extra capacity was also being provided on coaches, ferries and Eurostar and Eurotunnel trains.

On another forum, someone posted something they claimed to have seen in a Norwegian Newspaper

Leave 30 billion crowns in the trash can outside the Icelandic embassy, and we will turn off the volcano. Do not call the police".

The German Aerospace Center (DLR) Falcon 20E has now lifted off from Oberpfaffenhofen (near Munich) on the mission to map the ash concentrations above Europe from above and inside the cloud, after getting prepared for the mission in a record time of just four days (usually it takes weeks).

Since we only have three LIDAR stations for measurements over Germany (that all detect the ash), a pretty important thing to fill the gaps.

While I'm glad Europe is somewhat able to cope, I'm worried about what's going to happen if Ranier or St. Helens blows its stack and our air traffic is grounded. Amtrak has nowhere near the throughput of the European trains especially on its long distance routes.

You will survive. The German train network was also beyond its abilities on the weekend, but the situation got lessened by people quickly forming long-distance car pools.

Today, there are additional passenger trains now on the routes.

 

[Ghostrider]

By all means, launch probes into the cloud and find out the facts! That's what Captain Kirk would do, while shagging some alien babe.

You'll have to buy the noisy soviet jet engines, designed to work in the midst of the ashes of nuclear war

Seriously, i had an impression the USA was the land of cars and trains, where you could always take a bus or electrain even from one coast to another.
Not so?

 

[Urwumpe]

The problem is: Exactly that happens. The LIDAR stations are exactly made for this task, but they are limited to few spots and thus not enough for getting a complete map. Also, UK or USA weather services have more LIDAR stations than Germany as whole.

The complaints of the air lines, especially the German ones, are pure populistic lies - while the airspace limitation is based on a computer model, the model has real measurements as input.

Also, an earlier version of the computer model was already able to predict the Chernobyl radioactive cloud properly in 1986, so you can indeed rely on it.

So am I the only Orbinaut stranded?

 

[ar81]

{silly mode}My orbinaut sensors can detect life under Earth surface...
It seems eruptions are caused by their underground industry.
Could anyone send a message to the "intraterrestrial race" so they stop sending material towards our atmosphere? :lol: {/silly mode}

Wow, other images do not show the real magnitude of the problem.
That's just an amazing picture.

On another note, why the hell is the volcano still going? I finished the forging a couple of days ago. Can't someone just hit the OFF button? It's about 50 km under the mantle. Must be the 9 dragons I left guarding it...
