SUMMARY
Planes discharge static electricity during refueling using earthing straps connected before fuel connections are made. Static dischargers, also known as static wicks, are installed on the trailing edges of wings to manage static electricity during flight. The discussion highlights the importance of grounding to prevent sparks that could ignite fuel vapors, particularly in aircraft with electrically resistive materials like fiberglass. Proper grounding practices are essential in both aviation and military contexts, as emphasized by the mention of cruise missiles requiring grounding before maintenance.
