A plane crashed during an air show in Hungary on Sunday, killing two people on board and injuring four others on the ground, authorities said.

“According to preliminary information, in addition to the pilot, there was one passenger on board the aircraft (…) Both lost their lives,” Hungarian police said in a press release.

The tragedy unfolded in the Szekesfehervar region, 70 kilometers southwest of Budapest. Four people were injured on the ground, three of whom suffered serious burns, emergency services said. A woman, a man and a little girl are seriously injured. Little boy suffered minor injuries.

In a video uploaded to the local media’s website, the demonstration aircraft – a US Army T-28 Trojan built in 1951, according to the Hungarian press – makes a vertical descent before crashing and exploding.

“The small aircraft crashed near a parked car and caught fire,” police said in a statement.

“The crash happened very close to the site of the aerobatics show,” which attracted thousands of spectators, a spokeswoman for the national ambulance service told AFP.
