@Odericko, a bit harsh there, think Flo is just looking to see if there is another angle from within the comunity!
Security 101 will tell you not to move without reconciling a bag to a pax unless it is correctly handled as unaccompanied (Which KQ says it doesn't carry!), the plane should not have closed the doors let alone taxi before resolving that issue!
Good that the system, which ever variant it was stopped the plane getting airborne, guess they need to include a head count now perhaps
I suspect that Flo will answer you shortly however
