similar solo twr one, late at night. Approaching a/c gets no response to multiple inbound calls and landing info. As he get closer, still no reponse, so he puts the landing lights on aims the aircraft at the twr and waggles the rudder, then tries flashing the lights on an off. Still no answer.
Maybe the guys died at the desk..??
So he lands, taxis in, parks and ties down. Gathers his kit and walks to the twr and up the stairs. There's a newspaper over the console and, he's not dead, but fast asleep.
So he shouted in this ear "ABC, On the ground at XXX, Cancelling SAR"
That got his attention.!
