On March 16th a small experimental plane hit and killed a man on a South Carolina beach. This got me wondering why there isn't a horn or some other audible warning device required for them. Surely, there must be some way, independent of the other systems on the aircraft, to make it possible to trigger a horn or other warning device to get the attention of anyone on the ground?
The pilot of the plane in South Carolina had oil on his windshield and couldn't see the ground. His plane was essentially gliding. If there was such a device on the outside of the plane, he could have turned it on and maybe the man on the beach might have had time to get out of the way of this silent killer from the sky.
My question is, why hasn't anyone hooked up something like this on their own? I mean, we have obnoxious air horns at sporting events, so why hasn't some enterprising person created an emergency horn for a small plane? Your thoughts??
