Although the initial flash for the Evansville explosion is whiter.
A lot more of a big ball of flame in that one which is what you’d expect in a gas explosion.
The one this thread is about begins with a powerful blast at the base with a very bright white flash with a little orange ball blowing out sideways then the upward explosion immediately overwhelms the initial blast with a large dark cloud of debris.
The NJ blast has no dark cloud at all. Just a large ball of flame then debris and a smaller light brown cloud of dust below the debris not above it.
That’s my two cents and I’ve never stayed at a Holiday Inn.
