How about this one.
Recently attempted to travel with a whistling kettle as hand baggage (was a present for someone and not something I regularly travel with).
Was somewhat surprised when eventually allowed to take the kettle on board but made to go back to check in the whistle part. Was too late for checked baggage so I (and my whistle) had to be escorted to aircraft!
Maybe i've missed something here but could someone please tell me what the risk could be here?
Especially when there is a whistle on every life jacket under every seat on the aircraft.
Regards
