I don't have with me the specifics of that flight, but I can assure you that we always have inspectors on site to ensure that the flight plans can be respected. If there are delays at the airport, it means that the horses should not be boarded on the plane. They have to be provided with feed and water and a place to rest before they are boarded for the trip to their destination, which has to take less than 28 hours.
