And he was true to his word.

Y’see, Jackson started his own piano tuning business in Grand Rapids not long ago. So he had the tools and the know-how. And when he realized he could have a substantial stopover at ORD, he jumped at the chance.

Of course, he did things the right way – he contacted the airport to ensure the piano was still there (it was) and that he wouldn’t get in trouble for fixing it (he wouldn’t). He got in touch with HMSHost (they of food and beverage services at airports all across the country, including O’Hare) to mail his piano-tuning equipment to the airport, since some pieces of his equipment are sharp and wouldn’t make it through the TSA checkpoint.

“Everyone was all in on me tuning the piano, but even though I was just taking the basics, I didn’t want any problems going through security,” Jackson explained to the Washington Post.

Jackson had an 8-hour layover and it’s a good thing, too – the piano was in terrible shape and he needed just about all that time to get the instrument back to the point where it could just be played, never mind sound decent.

“It was in very rough shape — dust was everywhere, and there was a gluey substance under the keys that prevented them from working,” he said. “I’d never seen anything like it.”

He used his equipment to suck up dust, to pry each key off to thoroughly clean it, to scrape off gummy crap that was stuck to the inside, you name it.

“I figured out the reason the piano was such a sticky mess was because it was next to a bar, and people had spilled their drinks on the keys,” he said. “It was definitely the biggest challenge I’ve ever had.”

It took him 7 hours to clean the instrument – he didn’t even stop for lunch. But when he was done, the piano sounded, according to him, “really good.”

Before he left for his flight, he left a sign on the instrument that says, “No drinks by piano, please!” Hopefully people will listen.

The airline allowed him to fly home with his tuning equipment.

Since becoming a piano tuner, Jackson has started a YouTube channel, called The Piano Doctor, that showcases his “fixes.” And yep, ORD’s piano – his most challenging fix to date – is included. Here it is (it’s really kind of fascinating!):
