Montgomery Scott. Pleasure to meet you as well! As for the schematics? They are! I've always been interested in schematics and technical journals, so this was right up my alleyway so to speak! And about those tihngs...aye, right, torpedoes and beams. Oh they're simply...they're doohickeys. That's all! Contraptions I invented...last year, when I was bored! Let's not mention them until I've gone and patented them, aye? Wink wink.
You've made a good point also that shield can be overloaded, and that even if the polarities and frequencies on their shields COULD be changed, if they tried to fire through it, they might damage themselves more on their own. It would take a whole lot of in depth sabotage to do that, since it's theoretically possible - if one had a code or was able to crack it - to transmit it to the ship if they were able to weaken it enough, and bring the shielding down entirely.
Bloody hell! The possibilities are endless! We need to have drinks and discuss this sometime or other!
