The attached Access-To-Information documents, relating to live shipments from the Calgary Airport in Alberta in March 2015, describe the conditions under which several horses went down once loaded or prior to being loaded on a flight to Osaka Japan via Atlas Air. Of the horses that were taken back to be assessed after collapsing, one horse was found to be deceased in the crate. Note that the brand has been obscured. No explanation was provided for the cause of death, and it`s unknown whether a necropsy was performed on the deceased horse.
