Yet another deadly crash on Friday evening brought the total number of American service members to die during routine aircraft operations last week to seven, as a rash of recent incidents have reignited concerns about the dismal state of readiness the U.S. military has found itself in.

An AH-64E Apache crashed at approximately 9:50 p.m. on Friday night during a training operation at Fort Campbell in Tennessee. Both pilots died in the incident. The Apache and crew belonged to the 101st Combat Aviation Brigade, 101st Airborne Division, though their identities have not yet been revealed to the public. The cause of the crash has also not been revealed, but defense officials claim an investigation is underway.

“This is a day of sadness for Fort Campbell and the 101st Airborne, “ said Brigadier Gen. Todd Royar, acting senior commander of the 101st Airborne Division and Fort Campbell. “Our thoughts and prayer are with the families during this difficult time.”

This crash brought a particularly tragic and deadly week of American military aviation to a close, as seven service members in total lost their lives during non-combat operations. Two Marine Corps CH-53 Super Stallions went down last week, including one incident in Southern California that claimed the lives of four Marines on board. The following day, an Air Force Thunderbird pilot was killed when his F-16 crashed at Nellis Air Force Base in Nevada. Another incident in Djibouti on Tuesday saw a Marine Corps Harrier crash during takeoff, though the pilot  was able to safely eject.

“What has been evident to me for some time is now becoming clear to the American people. The readiness of our military is at a crisis point,” Rep. Mac Thornberry, R-Texas told lawmakers on Saturday.

Tragic as the past week has been, it has truly only been a continuation of a service wide trend. A lack of maintenance and training across the board has resulted in numerous incidents that have cost American lives, including two collisions between U.S. Navy warships and commercial vessels that claimed the lives of 17 sailors and a slew of other aircraft incidents like a C-130 crash last July that ended the lives of 16 Marines. None of these instances involved enemy contact – and many of these service members died as a result of seemingly avoidable accidents.

As these new incidents hit the headlines, many are prompted to ask questions about why these tragedies keep occurring, and further, why no one seems to have seen them coming.

The thing is, lots of people did.
