The jet erupted in a fireball when it came down shortly after takeoff.
A child patient, her mother, 2 doctors and 2 pilots were onboard when the plane – headed for Tijuana, Mexico – exploded.
All six people on board were Mexican nationals, according to Mexico’s foreign ministry.
A seventh person in a car on the ground was also killed – while officials say at least 19 others were injured.
