An airshow in Central Hungary became the site of tragedy on Sunday when a small plane crashed killing two passengers onboard. 

The plane, a small, propellor-driven 1951 American-made T-28, was carrying two passengers: a 67-year-old pilot and his 37-year-old son. Both were unfortunately killed, and four passengers on the ground (three in a family car) were seriously injured in the collision as well. 

The collision occurred at the Börgönd Air Show in Fejér County, Hungary, located just west of the capital city of Budapest. The airshow brought out thousands of spectators, who ultimately evacuated the airshow in the wake of the crash. 

The cause of the collision is not officially known yet, but video footage shows the plane performing rotations standard for airshows before ultimately bursting into flames. The plane ultimately crashed next to a parked car, whose passengers suffered severe burns from the flames. 

The incident is extremely tragic, particularly as air show accidents are increasingly rare these days. Air shows, however, often feature older aircraft whose safety features aren't always as technologically advanced. Indeed, the aircraft involved in this accident was over 70 years old. 

The airshow was eventually canceled altogether after the accident, understandably so. Our thoughts go out to the friends and families of those who lost their lives.
