A separate photo from the area shows a cloud of thick, black smoke rising into the sky.
According to the Stuart Air Show's website, a Grumman OV-1 Mohawk is scheduled to perform at the event.
A Grumman OV-1 Mohawk is a "twin-engine turboprop armed military observation and attack aircraft, designed for battlefield surveillance and light strike capabilities and was intended to operate from short, unimproved runways in support of United States Army maneuver forces," according to the Stuart Air Show's website.
The Stuart Air Show tweeted on Friday they've "had an incident involving one of our aircraft. All local and federal agencies are on site and investigating so that we may ensure the safety of our airshow before we continue."
