Electromagnetic Ejection for bunkers

I am making a bunker, it will have an electromagnetic ejection system. The ejection system works the same way as a coil gun. I would wear a hang glider with collapsible wings so when i was ejected i could fly to safety. Or i could use it to recon an area and spray suspected bandits with bullets.

The entrance has a spike pit that serves two purposes out. It keeps bandits out of my bunker but at the same time it will keep them alive in case i need to harvest their meat latter. Here is the blueprints.
