Your dad should be your hero. :)
There’s a good documentary you can get...narrated by one Captain James T. Kirk.
Here it is in action. AWESOME

If anyone has a Netflix streaming account it’s available too. Just watched this a few days ago. Very good documentary.
An excellent movie and I highly recommend it. The films of the explosions had been reworked to bring out all the color from the original film faded with age.
