Family members were in the area at the time.
"We are so grateful to them," said one of the teens' relatives Diane Caler. "This has been a horrendous shock, especially since we saw the helicopter land and fly, never dreaming that it was our kid that was on it."
Unfortunately, the driver, 16-year-old Kevin Monaco, was trapped and died.
One teen has broken legs and is badly burned.
The other two are expected to be OK.
