The Navy will ground aviation units on Monday as part of a safety review following several deadly crashes.

A Marine Osprey crashed June 8 in the California desert, killing five Marines during a training exercise. Over 40 people have died in Osprey crashes since 1991, according to the Washington Post.

As a result of the crash, the Commander of Naval Air Forces directed all non-deployed Navy aviation units to conduct a "safety pause" on June 13 in order to review risk-management practice and training in dangerous situations, Navy officials announced.
