I am sure Hotdog used to pop out of the flight deck now and then and unbolt the lavs and galleys to find that his beloved MRO had removed all the corrosion!
Maybe he used to descend into the lower lobe and unscrew the sidewall linings and have a good look at the P clamps on the wiring looms.....brushing aside the accumulated dust, he couldn't find a single wire trapped between the metal of the clamp where the rubber had carelessly been twisted aside.
Did he observe any wires behind those linings, so tight that that could produce a note similar to the "B" string of a guitar??
Did Hotdog climb up into the crown and pull the blankets back and find any cracks due to sharp impliments being used to remove sealant?
Perhapps not. But all the gauges and lights on his F/Es panel turned and lit up as they should.... and weren't those flightdecks so well presented.. lovely and clean!
How does that saying go about books and their covers?
