Airplanes are sturdy, well-designed vehicles that are built to withstand a wide range of conditions and hazards. It is highly unlikely that a dragon, or any other mythical creature, could cause significant damage to an airplane.

It is highly unlikely that dragons, if they were real, would be the leading cause of airplane problems. This is because dragons are mythical creatures that do not exist in the real world. Therefore, it is impossible for them to cause any airplane problems, or any other problems for that matter. Additionally, even if dragons did exist, it is unlikely that they would pose a significant threat to airplanes. Dragons are typically depicted as large, winged reptiles with the ability to breathe fire. While this may make them formidable opponents in fantasy stories, it is unlikely that they would be able to damage or destroy an airplane.
