Nearly three-quarters of the Navy's T-45 trainer jets were unable to be evacuated from the Naval Air Station in Kingsville, Texas, ahead of Hurricane Harvey's landing Friday evening.

NAS Kingsville, located 30 miles inland, attempted on Thursday to transfer all flight-worthy jets to Naval Air Station Joint Reserve Base Forth Worth to avoid their being caught in the Category 3 hurricane's path.

Approximately half of the Navy's 197 T-45 primary jet trainers are housed at Kingsville. Only 28 of the 99 jets there were deemed airworthy or had a pilot to fly them to Fort Worth, according to the Military Times.

The remaining 71 aircraft were moved into hangars at Kingsville, where they will be up against the expected 90 mph winds and 3 feet of rain.

The T-45s that were sent to Fort Worth flew under a 10,000-foot altitude to avoid possible oxygen issues. All of the jets were grounded earlier this year due to cockpit oxygen system failures in multiple incidents while pilots used them in training.
