Which of the following is not an authorized method of transporting remains in CONUS?

The reason chartered or private aircraft is not considered an authorized method of transporting remains within the Continental United States (CONUS) is associated with regulatory and logistical complexities that may not adhere to safety and standard practices established for such sensitive transport. The proper handling of remains requires adherence to specific protocols and standards to ensure dignity, security, and compliance with legal frameworks.

While commercial airlines, government vehicles, and train services have established procedures for transporting remains, including proper handling, notifications, and necessary documentation, chartering private aircraft may not guarantee the same level of compliance or oversight. Such operations can vary significantly in terms of the protocols they follow, which raises concerns regarding the appropriate treatment of remains during transport. Therefore, using chartered or private aircraft does not align with the authorized methods that ensure the respectful and secure transportation of human remains in CONUS.
