Just came back from seeing the movie. Really enjoyed it. The special effects were simply awesome - now I've seen the movie I need to go search to find out just how they did all that zero g special effects. Only one problem with it and that was in the implausibility of some of it. Generally good realistically (like no sound in space unless they're touching something) but flying between two spacecraft by eye using a fire extinguisher as propulsion? Come on! Oh, and you get to see Sandra Bullock in her pants - looking good for 50.

Basic physics. A fire extinguisher would provide quite a lot of thrust. Assuming a man in a suit had a mass of 100 kg and the extinguisher had a compressed gas mass of 1kg with an expansion rate of 5. In order to gain thrust and allowing for the co-efficient of restitution he would accelerate at 5 m/s/s for aboiu 5 seconds with the rate of acceleration reducibg as the pressure dropped. Certainly able to get to about 25 m/s

The basic physics isn't the issue, the issue is the implausibility of the actions. Without giving too much away, she aims a spacecraft by eye toward another (they're probably close enough that orbital mechanics doesn't come into it too much) and fires the rockets. Then, she uses the explosion of pressurised air from her craft to blast her toward the other ship as she zooms past, and the. Uses the fire extinguisher to steer her to the destination . Physically possible but so entirely implausible...

Yes, well that is equally implausible.

It's not the steering that's the problem. It's slowing down... X|
The only instant messaging I do involves my middle finger.

Slowing down is merely a matter of hitting something far more massive than yourself.

Which leave the minor problems of 0) Not bouncing right back off again 1) Surviving the impact Neither of which movie makers ever seem to consider! :laugh:

exactement - which is where the realism loses out to the story telling. Still a damnably fine movie though.

That's the A-Team. They are professionals.

I would have thought you unloaded the ammunition if it was going in a cargo plane...
