Lightning Protection, Please

So lightning has put the Transponder Operations, at both Gates, out of business. At both gates at the same time? Is that even possible? What really happened here?

Lightning protection is not mystery. Did we protect our gates adequately? Did we have any Lightning Protection at all?

I wonder if this is another lack of corrective action, like the small one paragraph Contract for the Multi-Million Dollar Road repair, or the lack of following the DA's Advice on the Broad Band initiative? No thanks on CV wide WiFi.

Here is a brief synopsis from Wikipedia on lightning Protection.

Lightning protection system[edit]

lightning protection system is designed to protect a structure from damage due to lightning strikes by intercepting such strikes and safely passing their extremely high currents to ground. A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes.
Lightning protection systems are used to prevent or lessen lightning strike damage to structures. Lightning protection systems mitigate the fire hazard which lightning strikes pose to structures. A lightning protection system provides a low-impedance path for the lightning current to lessen the heating effect of current flowing through flammable structural materials. If lightning travels through porous and water-saturated materials, these materials may literally explode if their water content is flashed to steam by heat produced from the high current. This is why trees are often shattered by lightning strikes.
Because of the high energy and current levels associated with lightning (currents can be in excess of 150,000 amps), and the very rapid rise time of a lightning strike, no protection system can guarantee absolute safety from lightning. Lightning current will divide to follow every conductive path to ground, and even the divided current can cause damage. Secondary "side-flashes" can be enough to ignite a fire, blow apart brick, stone, or concrete, or injure occupants within a structure or building. However, the benefits of basic lightning protection systems have been evident for well over a century.[11]

  1. Several months back, our transponder lane was down. The story out of UCO was that the system was struck by lightning. A man that I know extremely well happened to be walking at the gate when the repair people were there fixing it. He struck up a conversation with the men, and asked what happened. He was told that lightning had nothing to do with the downed system. Now isn't it a coincidence that once again our system was struck by lightning? I guess lightning is just drawn to Century Village and only to our transponder system. How did we get so lucky? More crap shoved down our throats. Does anyone in UCO know how to tell the truth, even about such a small, non-important thing as our system being down?
