We are not positive exactly when the cargo was unloaded, since the crew was onboard (being held hostage) for at least a year.
There are still lots of questions as to what exploded, and what all was in that warehouse that went boom.
Ok thanks, just the title of the article suggests there was some mystery to this ship, when I thought it was pretty well know it ended up there and didn’t leave, that’s why I asked.
Yes certainly questions around what started the fire in the ‘fireworks’ warehouse. There were indeed fireworks there (we could see and hear them going off in the initial fire), however that doesn’t mean there weren’t other munitions or a ‘missile factory’ or whatever operating there.
However given the orange/red cloud of smoke seen after the second explosion, it is quite clear that it was AN, the orange/red smoke is a telltale sign of the nitrogen oxide which is produced in an AN explosion.
