One would hope that instances when forbidden DGoods are carried on passenger aircraft are nil. The system that polices the items that reach the hold both as passenger baggage and cargo is strong and the opportunity for unproved items slipping through the net very low.
This however is dependent on the individuals responsible for ensuring that the system works and do the job correctly, honesty in the identification of items by the shipper and origin, and training to ensure that the responsible individual is trained and qualified.
ignorance of the regulation or lack of know age when declaring content of shipment, releasing cargo or any item going onto any aircraft is No excuse and the full order of law should be applied against them not complying and endangering life.
