Hey Paul, don't give up so fast.  Granted there's some problems with the 
theory as many of the list members have mentioned.  However, you won't 
know until you try.

So, let's look at some of the options.  First, there's the idea of one of 
the disposable lenticular cameras.  Of course you'd need a way to trip the 
shutter and the interocular distance is way too short for your distance 
estimates.  Still, it might be worth trying a few launches just to see 
what comes out.  I expect you'd have to use "D" sized engines to lift the 
payload though.

How about a couple of those nosecone cameras which use 110 film?  Have 
them rigged with a staging rocket so each camera will fire with each stage.

Or, maybe changing hobbies to R/C planes might be in order :-) :-)

Now you've got me wondering how to do something like this.  The longest 
rocket (Estes kit) I ever launched was about 36 inches long.  It used "C" 
engines.  So, a longer rocket with "D" engines might be a viable option.  
Mount one mini-cam at the nosecone and one near the engine.  Build the 
rocket with glider type wings (ala Shuttle design) and a detachable fin 
section (which would house the parachute).  This would launch the rocket, 
start it into a glide (with the cameras facing down, then pop the tail 
section releasing the chute and the camera shutter.

Another alternative would be to find a lightweight "point & shoot" 35mm 
that will continuously fire when the shutter button is pressed.  Then a 
simple spring loaded arm that would press the shutter button as the engine 
ejects would start firing the camera.  That way you could select any 
number of frames to view your 3D.  

I think your best bet would be to develop some sort of glider based rocket 
that would orient the camera downward as it glides back to earth.

Hope this helps,
Ron
