I remember a few months ago when the ship crashed on the Helenia City District. The news claimed it was an accident, but one of the survivors claimed that it was on purpose, he then got interogated by the RBI (Royal Beureau Investigation) about the incident.

I was gonna type some more details, but the cause was classified in order to keep the people from a chaotic panic. I know this because I'm one of the interogators.

It's for the best to claim it to the public as an accident.
