While human beings can apparently urinate in the aisle of a passenger jet without the plane needing to make a pit stop, and it’s fine and dandy to fly a plane full of people sick with the norovirus to their destination, a little dog poop on a US Airways flight is cause to bring a transcontinental flight to a screeching halt and bring in a clean-up crew.

This is what happened earlier this week aboard the US Air flight from L.A. to Philadelphia, when a dog in the cabin just couldn’t wait a few more hours to go for a W-A-L-K.

The canine was apparently brought into the cabin as a service animal for one of the passengers on the flight, but lost control of his bowels. It didn’t help that passengers (and the dog) sat on the tarmac for a couple of hours before they even took off.

“About an hour into the flight, I started smelling this terrible smell,” one passenger tells Inside Edition. “I look up the aisle way and there’s a dog pooping right in the middle of the aisle. It’s a big dog, three or four feet tall or long, and he was just going!”

He says that the smell was so bad that some people were dry-heaving and others actually vomited.

And it got worse when the dog let loose for a second round of poo. The passenger says that the cabin crew ran out of paper towels, at which point the pilot announced they would be making an unscheduled pit stop.

So the plane landed in Kansas City, where a cleaning crew boarded and took care of the toxic dump.

The passenger says the dog’s owner was apologetic and offered to send Starbucks gift cards to everyone.

Of course, this being the age of Twitter and in-flight WiFi, the entire ordeal was shared in real-time by passengers. You can read a mess of poo-related Tweets at NBC Philadelphia.
