Ann Romney's plane was forced to make an emergency landing in Colorado moments ago ... after a fire broke out in the cockpit and the cabin filled with smoke.
According to a Romney spokesperson, the plane landed safely and no one onboard suffered any injuries.
The rep posted a statement on Twitter saying, "All okay. Thank goodness."
Upon arrival, the fire department rushed to the plane in an effort to find the source of the smoke. A spokesperson for the Denver Fire Dept. said the smoke came from a "small fire in the cockpit."
The plane was heading from Omaha to Los Angeles.
Mitt Romney was not onboard the plane, he was in Nevada during the mid-air emergency ... where he was appearing at a fundraiser.
