On our domestic flights in Nam its usual to carry passengers' chooks and dogs. Our loading rules (for 737) is chooks in the rear cargo hold and dogs in the forward.
This day someone screwed up and put the chooks in the forward hold with a dog! It was my flight to Da Nang that day and enroute I could feel some thumping going on under the floor. On arrival at DAN I immediately went out to see what was going on down there. I expected to see some cargo shift. When the door opened some terrifyed blood-spattered chooks flew out, and here was the pooch staring at me from the edge of the hold with a bloodey huge grin wagging his tail with several feathers still stuck to his bloodied chin! Hed broken out of his wooden cage when he heard the squawking and laid into the chooks after smashing their wooden cages.
He certainley had no complaints about the inflight meal service!
