This type of accidental gas explosion, where there is little or no fire in the unobstructed space that the explosion vents to, but a lot of high speed shrapnel and debris from the destroyed "confinement boundary material" is consistent with the type of injuries sustained by the victims reported by the receiving hospitals of last week's Makati blast, as well as the notable absence of fire in the first second and third floor levels affected. (However, we should hear about extensive fire or flame damage in that basement after the authorities announce further findings of what they observed down there.)
Have a good night's sleep for a change everyone! Time enough to think of the political and publicity fall-out tomorrow. For now I will only say:: God Bless America (and the FBI!) God Bless the Philippines!
