My impression is that "the sceptics" were not skeptical--I'll revert to my American spelling--about the cause of this event, whatever it was or wasn't, they were skeptical about the OP's SLF description of the event as verging on panic and fear. I remain skeptical about that.
Understandable that confusion when different incidents are merged into one specific incident titled thread.
Indeed, to sort this out one has to await the reports from the two different investigating agencies to even draw comparisons.
IMO these incidents need sorting out and assessed for corrective actions.
