Another mysterious aircraft crash occurred, although this one less lethal than those in the past.

Late Sunday morning a United States Marine Osprey conducted a so-called “hard landing” during a training session with two other helicopters. The plunging of an MV-22 Osprey into the ground at the Bellows Air Force Station in Windward Oahu caused one Marine’s death and the injury of 21 others.

Witnesses on a nearby beach claim to have seen three helicopters circling in the air, dipping down, and suddenly only seeing two. Black smoke, along with panic, filled the air.

Those injured were rushed to local hospitals and treated immediately. As of Monday morning all have been released, excluding one Marine in critical condition and three still hospitalized. The family of the deceased remains in mourning over the sudden death of their loved one who died in what was believed to be a reliable aircraft.

The cause of the crash is yet to be determined but an investigation is being held on the matter.

It seems as though history has repeated itself. In 2000 the Osprey program came close to being shut down after two test crashes ended in the deaths of Marines. Perhaps it is time for further safety precautions to be made, or possibly for the Osprey program to come to an end.
