I was thinking that it didn't get shot down, but someone was overzealous in their cocaine scrapin', line makin' plane flyin' cocaine snortin' frenzy. In their line making efforts they cut out too much of the wall and it broke open. The pressure sucked a bunch of stuff out, ruined so many fat lines!!! (NOOOO!) made the hole bigger and bad enough to put down the plane,
That was the end of cocaine plane. Fell to the earth like Icarus. He flew too high, too close to the sun. Cocaine plane just got everyone too high. I can imagine some people may dismantle it and take home a propeller blade or two or put a wing in the back of their truck.
