Officials in Denver have confirmed no injuries were sustained by the pilots and passenger of two planes that collided in mid air despite one plane suffering severe damage to its tail section.

The planes collided while coming in to land at a local airport. One pilot requested an emergency landing after the right engine failed without realising the plane had been almost torn in half. The second pilot and passenger deployed a parachute system to return safely to ground.

The National Transportation Safety Board has four people investigating how and why the planes collided and expects to finish its investigation in twelve to eighteen months.
