In case you don't get it, we are a group with great imagination!  How about
switching from modle (I assume you mean "model"?) rocketry to hot air balloons
or something?

Trying to take stereo pictures from a rocket presents the following
problems:

1. The rocket is moving in the wrong direction (vertically instead of 
   horizontally).

2. It is at a high elevation which makes a single stereo camera useless (we
   often rely in the 1/30 rule which states that the separation of the lenses
   should be 1/30 the distance of the closest object; if the closest object
   is a flat ground, then more separation is recommended).

3. It is moving too fast, resulting in blurred pictures for the slower
   shutter speeds of most cameras.

I really don't see a solution to these problems but I might be lacking
some of the imagination displayed by my fellow stereo photographers quoted
above.
