Horror moment plane drops from the sky like a stone and crashes onto busy road killing two on board & injuring biker

THIS is the horror moment a plane drops from the sky and smashes into a busy road - killing two on board and injuring a biker.

Shocking footage shows debris flying across the street in Ecuador as stunned witnesses watch on in disbelief.

The crash on Tuesday claimed the lives of Captain Diana Estefaníaiz Solis and Cadet Juan Andrés Pacheco Ramírez.

According to reports, they were known as the "Dame and Knight of the Air".

Shocking footage shows the aircraft plummeting to the ground while on an instructional flight.

Pedestrians are seen stopping in their tracks and staring as the plane rests belly-up in the middle of the packed street.

The deadly event occurred on Eleodoro Solorzano Avenue - a lively street in the city of La Libertad.

The plane's body does not bounce or skid along the road and instead just stops dead once it smashes into the ground.

A biker on the ground was injured when he was struck by a piece of the plane.

He was riding along the road when he was struck - seen trying at the very last second to swerve out of the way of the debris.

The man is seen coming off their bike during the huge crash.

A white car was also caught in the chaos and partially crushed.

In a statement shared online, the military forces of Ecuador commented on the tragedy.

They wrote: "The military and civilian personnel of our institution are in mourning, for the unfortunate death of Captain Diana Estefaníaiz Solis and the cadet Juan Andrés Pacheco Ramírez, who in life were highlighted 'Dame and Knight of the Air'."

“Our sincere condolences to the families and friends for such irreparable losses.

“We raise our prayers to the Almighty to receive their souls in his holy kingdom.”

Support is being provided to the families of the victims, authorities said.

An investigation is currently being carried out to determine the exact cause of the accident.

The aircraft belonged to the Superior Military Aviation School of Ecuador.

It is unclear how extensive the motorcyclist's injuries are.
