Hi,

Can an aeroplane be designed in such a way incase of any emergency, danger, the passenger cabin is detached from the main plane and parachuted down to earth to avoid loss of life?

Thank you

I'm sure it could be, but I don't know that it would do any good. If the danger was fire in the cabin, or inside the cabin wiring and circuitry, the passengers would be dead long before they hit the ground. If the danger is a hijacking, in all probability, some of the hijackers will be in the cabin.

Another problem would be the cost of designing such a plane. Obviously, ticket prices would go up as a result of the higher cost of making such a plane.. They could easily be 5 or 10 times what they are today. I think you'd see an explosion of passenger service in railroads and a very significant drop in air travel.

There is a private airplane version that is in use today. I believe it's model name is the cirrus. http://www.msnbc.msn.com/id/6749412/ for an article.

All of the reasons that Dorian Point out still apply. In addition most accidents happen near the ground where a parachute would not have time enough to work well. The most recent example was the 777 Crash in the UK.

We'd save many more lives with better crash systems for automobiles,and buses.

As Peteeo pointed out, such systems already exist on some small planes. However, I once read that a similar system for large aircraft such as a commercial jetliner would need several parachutes each as large as a football field to land it safely, and just wasn't practical.

There seems to be pros and cons to their use as it is.

Maybe the F-111 had the largest possible example of such a system.
