I'm sitting reading all the comments and compelled to state the facts as I understand....Why would you want to stop the credit card payment to the shipper when the shipper did his job?
1) The crate(s) were delivered from the taxidermy shop (on a truck) to the shipper.
2) The shipper put it on a truck and delivered it to the Airport at JNB.
3) In this case at the airport, Delta handlers put the crates on a plane.
4) The plane takes off from JNB and lands in Atlanta, all good (according to what I read)
5) Delta continues routing the crate(s) by truck to final destination, Baltimore, where damage is reported by Delta upon arrival
The purpose a shipper offers insurance is to make sure that any damage or loss from departure to arrival at destination, is covered should something happen. This is because the liability of airlines is minimal due to federal regulations. If the shipper does not offer insurance, it is incumbent upon the hunter to get it. This is true for trophies that are mounted OR dip and packed. (For dip and pack the risk is more loss than damage.)
Regarding the crating/boxing of trophies: there are specifications for crating so if something was not up to specifications, the airline would not even accept it at origin for obvious liability reasons.
Bottom line, knowledge is power and prevention is key. Once the damage is done, everyone looks to place blame but the blame is in negligence of knowledge to protect against a damage like this. The transportation industry is very risky and insurance is the only way to safeguard against things we have no control over.
Trophies are invaluable to a hunter.....that is why we make sure all our hunters are covered for all risk, door to door and not just the airport of arrival. Once trophies clear, they have to be trucked again to a residence or taxidermist. What happens when a crate is damaged in that stretch of the journey? Not the airline but the trucking company and there is no coverage at all!
