What would be the result of an American Airlines Md-80 striking a weather balloon at FL310 going around mach .76?

I think the balloon would get sucked into the engines.

The MD80 would probably bounce off the balloon.

I want some serious analysis as this almost happened on Sunday.

Well, let's go with the 'balloon getting sucked in the engine' theory. It would probably core the engine, and the plane would have to make an emergency landing at a suitable site. I've heard about jet engines sucking in volcanic ash, with similar results.

I don't think so much would happen. All engines are built to manage a collision with an objekt in the air. I saw pictures from the testing of on e engine for the 777 and nothing happend when they throwed a bird in it. So I don't think it would be affected.

Just like birdwatching - without having to be so damned quiet!

Booyala-Where did this almost happen?

I believe that the impact would probably cause comparable damage to that caused say by the impact with a large bird - like a goose. If the instrument package happened to be injested by an engine when you could write off that engine. It's not too hard to imagine a catastrophic scenario where the flight crew was incapacitated or worse, afterall, pilots have been killed as a result of bird strikes, but it's highly unlikely.

I dont think a weather balloon would have a whole lot of effect... they are very thin and would get melted near instantaneously by the engine core. The balloon is very light and doesnt have much mass at all... so i would say it would be less critical than a birdstrike.

About 10 nm miles north of the RZS VOR

As far as I know they don't just send the baloons up but it includes some instruments to measure temperature,pressure etc.So this baloon could have some package attached to it.And now think about it colliding it from the cocpit window.The result could be disasterous.On the other hand loosing an engine, can still make it to ground safely but anyting hitting onthe fuselage can seriously effect the aerodynamics in my opinion.
