A long-standing, physically demanding job in the U.S. Air Force is getting a high-tech upgrade. For decades, aircraft technicians have been crawling into cramped, dark fuel tanks on KC-135 Stratotanker aircraft to perform critical maintenance—cleaning sealant, tightening rivets, and checking for leaks. The work is dangerous, slow, and often hindered by poor visibility, limited communication, and the risk of mistakes. Now, a new system called the Integrated Respirator Information System, or IRIS, is transforming this essential but grueling task. Developed by MetroStar and ActionStreamer, IRIS is a wearable headset that mounts directly onto a technician’s respirator mask. It includes a high-definition camera, two-way audio communication, and a hands-free light. The system streams live video to a mobile workstation outside the aircraft, allowing support teams to see exactly what the technician sees in real time. This enables remote guidance, faster problem-solving, and better coordination. The idea began with two Air Force maintainers who saw potential in ActionStreamer’s first-person video technology, originally designed for athletes. After years of advocacy and testing, the system is now being used at Royal Air Force Mildenhall, a key refueling hub for U.S. operations in Europe, Africa, and the Middle East. Initially, technicians were skeptical. “They were a little apprehensive,” said ActionStreamer CEO Bob Lento. But within days, their attitude changed. “We were taking the cart out of the hangar, and they were like, ‘Wait a minute, where are you going with that? We need to use that now.’” The system’s ability to reduce delays and improve accuracy quickly won over the team. The job has always been risky and time-consuming. Technicians enter through a narrow access point under the wing, contorting their bodies in tight, fuel-scented spaces. They wear heavy protective gear and rely on respirators connected to external air supplies. If they need a tool, they must pull off their mask, shout, or tug on the hose—delays that cut into productive work time. Mistakes, like applying sealant in the wrong spot, can extend repairs by days. IRIS eliminates many of these bottlenecks. With live video and clear audio, the support team can guide the technician through each step, verify work, and flag issues instantly. Recorded footage also helps resolve disputes—such as when one shift claimed a fuel puddle had been cleared, but the next shift found it still there. IRIS footage revealed the original team had done the job correctly, but a new leak was present, allowing for faster, accurate repairs. The system also enables remote expert consultation. Instead of waiting for specialists to travel to the base, teams can launch a video call and show the exact problem in real time. This reduces downtime and improves decision-making. Looking ahead, AI is being integrated into IRIS to further streamline the process. As technicians work, AI agents analyze video and data to anticipate next steps, suggest actions, and even fill out forms automatically. This reduces time spent on repetitive tasks, allowing maintainers to focus on complex work. Early results are impressive. At Mildenhall, inspections are running 60% faster, and no safety incidents have been reported since IRIS was introduced. According to MetroStar, the system could save 35,000 maintainer hours and add over 7,000 aircraft availability days annually. The success of IRIS is credited to the technicians themselves—those on the front lines who pushed for change. As retired Air Force Maj. Gen. Cedric George put it, “This is not for the faint of heart, it’s dirty work.” But with IRIS, they’re ensuring future maintainers won’t have to endure the same hardships.
