A small plane crashed near a major highway in Jundiai, a city in Brazil's Sao Paulo state, killing the four people aboard, all members of the same family, the fire department said.

The victims of Saturday's crash have been identified as Arnaldo Soares dos Santos Neto, the plane's 50-year-old pilot; his wife, Kenia Maria Tubertino dos Santos, 49; and their children, Ana Luiza, 19; and Arnaldo, 14, police said.

The plane went down at kilometer 65 of highway SP-330, known as the Anhanguera and one of the main highways in Sao Paulo state.

The aircraft burst into flames when it hit the ground, burning the occupants.

The accident happened around 12:30 p.m. shortly after the small aircraft took off from the airport in Jundiai, located 55 kilometers (34 miles) from Sao Paulo.

Drivers slowed down on the highway to look at the burning aircraft wreckage, causing a nearly four-kilometer (2.5-mile) traffic jam, highway operator CCR AutoBan said. EFE
