@mroinsider: ✈️ Those tiny holes under a jet engine have a purpose. Aircraft engines and nacelles contain carefully designed drainage paths that allow accumulated fluids to leave controlled areas safely. During maintenance, engineers pay attention to these areas because unusual fluid leakage or contamination can sometimes provide an early indication that something needs further investigation. It’s another reminder that aircraft engineering isn’t only about the huge engines and wings. 🔧 Sometimes the smallest details matter the most. 👀 Did you ever notice these holes on a jet engine before?
