News reports that the man had earphones in his ears and did not hear the plane approaching.
So the poor beachgoer couldn't hear the horn
or the squealing wheels of the aircraft gliding in at him!? My sympathies....
I can see it now,
FAR 23.1463, External Warning Devices
(a) All aircraft shall be equipped with external aural warning devices, which are loud enough to warn persons on the ground of the aproach of the aircraft in any configuration,
(b) All such warning devices must be operable with requiring engine power,
(c) The actuation shall be by push force in the center of the control wheel, or stick. The force required to actuate the aural device shall not be such that a pitch change is commanded when actuated,
(d) No warning device shall emit noise levels exceeding those already approved for the aircraft model.
And we wonder why aviation is so heavily regulated!
