"I got a call about 10:15 and they tell me that there's a couple of airplanes on fire at the airport."
When airport manager, Jimmy Wells, got to the scene, his first concern was safety.
"These airplanes were close to a set of hangar buildings. It could have been a disaster."
Crews put the fires out in a matter of minutes, but what they found when they did, was a bit puzzling. Both of the turbo-prop Cessnas were spray-painted. One read, "This is our airport." The other had some choice words for a man named "Rob."
"We're not sure why that happened. Like I said, it's still under investigation."
A check of the FAA's database shows a Terre Haute, IN, company owns both planes. The same company owned a plane which crashed near the airport this summer.
"There's a lot of questions right now and hopefully, we'll have a lot of answers in the next few days."
Those answers could be the key to solving this disturbing mystery. 33-year old Rusty Bogue was the pilot killed in the August crash.
Investigators say flight crews knew of a problem with one of the plane's engines, but the NTSB hasn't released its findings of what actually caused the crash.
