Loud Explosions in HPP

[kalianna]

I was awake and happened to be looking out the window when I heard five loud explosions mid-HPP. I saw the flashes mauka and the explosions happened about 3 seconds after each flash so we must have been pretty far away, but it DID shake our house and louder than even the best our two local idiots have to offer. I also thought it was propane tanks at first but I could hear the little "whoosh" that indicated they were being launched. Wondering where they appeared to be coming from in Orchidland.
