from "LPG", "traces of C4", "traces of RDX", "äctivated by cellphone", to methane gas buildup. napakalawak naman ng range of theories on this. di naman siguro madaling magkamali sa pagdetect ng C4?

question: if it was indeed methane+diesel that caused the explosion, wouldn't the whole G2 have caught fire? alangan namang sumabog ung methane at ung diesel hindi sumabog? imho(di naman ako explosives expert) the methane could have been odorless, and burned clean hence no residue...but the diesel fuel would've stuck to the sorrounding structure and burned right?
