Flytrex, another Walmart partner for drone delivery, introduced DSN Yariv Bash, CEO and founder of the company, commented: “The drone delivery industry is at a pivotal moment where the focus is shifting from regulatory approvals to achieving true commercial viability. Walmart’s decision to discontinue DroneUp services underscores the need for a robust system that both meets regulatory standards and delivers on the promise of cost-effective and scalable operations. You can’t deliver groceries in a Bentley – it’s just too expensive. The key to the industry’s future success is developing solutions that are more affordable and efficient than existing alternatives.”
