An American military helicopter crashing is never good news. But, in such a situation, the following is truly the best case scenario.

On Wednesday, a Marine Corps CH-53E Super Stallion crashed near the Barry M. Goldwater Range in Yuma, Arizona. According to a USMC spokesperson, not a single Marine of the five aboard the chopper were injured.

Based at the 3rd Marine Aircraft Wing at Miramar in California, it was in the middle of a training mission at 1 pm local time when it fell from the sky.

More from the Marine Corps Times:

Although Marine aviation saw a spike of crashes toward the end of 2016, the first few months of this year have been relatively quiet. The last major incident was on Dec. 13, when an MV-22B Osprey from Marine Medium Tiltrotor Squadron 265 crashed in shallow water off Okinawa after its rotor struck a refueling line, according to the Naval Safety Center.

That same day, another Osprey’s landing gear failed, so it landed on reinforced cushions at Marine Corps Air Station Futenma.

The crash is currently under investigation.
