What's Wrong With This Engine?


Take a close look at this engine.
Click on the picture to enlarge it.
The production date is November 11, 1974.

It was flown this morning, July 19, 2010
For a 35 year old engine it performed beautifully.
What's wrong? Can you figure it out?
The answer will be posted in a day or so.

  1. 1/2A3-2T is not an upper stage motor. It's a single-stage motor.

  2. EGE,
    You got it!
    This is obviously a misprint, someone didn't change out the print roller between runs. I didn't notice this until after I used the engine this morning. Otherwise, I would have saved it as a collectable. It's probably only valuable to me or post on a blog.
