THREE young people are lucky to be alive after a spectacular crash in Sydney’s North West overnight.

A Mitsubishi went airborne off a garden retaining wall, bounced in a front yard, before landing on top of a Honda sedan shortly after midnight on Sunday morning.

The male driver of the white Mitsubishi allegedly ran from the scene, deserting his two young female passengers.

The car was driving down Aiken Road in West Pennant Hills when it mounted the kerb, smashed through an electrical box, and destroyed a fence.

It then went airborne from a retaining wall, flipping before crushing landscaping equipment which happened to be parked in the front yard of the house on Aiken Road.

Miraculously, the car somehow kept going, landing upright on top of another sedan in the driveway.

It also smashed the house’s garage wall in, causing structural damage.

The two female passengers could not remember how the car had caused so much damage yet had apparently injured no one.

The pair said they completely blacked out during the dramatic scene.

The family inside the house were suddenly woken to “big, big bang” and wailing car alarm in the otherwise quiet suburban street.

“I thought it was a bad dream,” she said.

She said the young women were waiting outside their home but the alleged driver of the car had vanished.

“Coming out to see that, I thought someone must have been hurt. I came out and tried to help the girls, but the girls said they were okay.”

They said it was remarkable that none of the occupants appeared to have sustained injuries, and the car had landed in an upright position, rather than continuing to roll.

The family said the young women apologised for their friend who crashed into their home.

Police from the Hills Local Area command are now pursuing inquiries as to the identity of the alleged missing driver.

Firefighters attended the scene and stabilised the garage wall.
