TAMPA, Fla. (AP) — An experimental plane that may have been having trouble landing struck another that was taxiing at an airfield Saturday, setting both on fire and killing two people, authorities said. Two people were critically injured.

The plane trying to land crashed into another on the ground around 8:30 a.m. at Arthur Dunn Airpark in Titusville, said Scott Gaenicke, spokesman and division chief for Titusville Fire and Emergency Medical Services.

Both planes were single-engine and amateur-built, officials said.
