These positions involve the secure and rapid transport of sensitive or time-critical items. An individual filling this role accompanies the consignment, typically via commercial airline, ensuring its safety and integrity from origin to final destination. For example, a technician might be dispatched to personally deliver a crucial component to a factory facing imminent production downtime.
The advantages of this method are significant, particularly when speed, security, and control are paramount. Direct oversight minimizes the risk of loss, damage, or theft. The immediacy offered contrasts sharply with standard shipping procedures, proving invaluable when encountering tight deadlines or handling irreplaceable goods. Historically, this method arose from the need for guaranteed delivery in situations where standard freight options were inadequate.
