Most airport towers are built with Lightning Protection Systems. However, serious incidents do occur.
A well reported incident of lightning strike on the airport tower at Baltimore/Washington International (BWI) Airport injured an air traffic controller and revealed a potential vulnerability that could affect towers at other U.S. airports.
In the BWI incident the Lightning Protection System failed, most likely because the cable was cut during a construction project several years earlier.
FAA has established its lightning protection requirements for the following:
- airport control towers
- Navigation and Approach Lighting Systems (ALS), including airport beacon, PAPI, VASI, RAIL, REIL, VOR, ILS, and MALSR systems
- weather and airport advisory systems, including RVR, ATIS, AWOS, and ASOS
- high and low voltage electrical and communication cabling systems; fiber optic placement, splicing, and testing; and airport grounding systems
