Disney has some pretty cutting edge technology. The airlift system for air launching fireworks is really, really amazing. It fills several hundred Kevlar wrapped PVC-type tubes in a few seconds. The system knows how many mill-secs it takes to load each one and if it fills outside of the parameter it logs an exception report. Same for dP/dT on discharge of each tube, to measure stuck release valves.

Initially to test the prototype concept they took plastic balls, put cheap kids walki talkies in them with the talk button taped down and blasted a white noise upwards and listened to the doppler shift from the projectile to calculate acceleration. Many Disney Imaginners graduated from MIT, Cal Tech, etc. One of our top ride designers is a good friend of mine and is having dinner at our house tomorrow.
