@ 58 seconds in the slow mo video

you can see the yellow light begin to enter the screen. At this point the sky and treeline are still visible underneath the yellow streak with no gas tank in sight. I've never seen gasoline silos as tall as a factory before. Gas storage that big is usually underground like at gas stations and you would think they'd be extra careful at fertilizer plants and prepare for fires. Lastly the short whistle noise before the explosion is the icing on the cake for me. Not saying you are wrong, but to reject the Original posters view so vehemently was unnecessary.
