The Navy will resume training flights in its T-45 Goshawk jets in July after they were grounded due to oxygen deprivation incidents, according to Vice Adm. Mike Shoemaker, commander of Naval Air Forces.

Instructor pilots will start flying the aircraft at facilities in Texas, Mississippi and Florida in early July and students will resume flight training later in the month with the onboard oxygen generating systems that have been suspected in a rash of hypoxia-like symptoms, the admiral said in a release Thursday.
