Federal investigators say a fatal air ambulance crash in New Mexico occurred after the crew lost GPS navigation during a scheduled US military jamming exercise. The incident has renewed concerns about aviation safety, particularly whether cockpit navigation systems and procedures are sufficiently resilient to deliberate GPS interference.

The National Transportation Safety Board linked the crash to the loss of GPS guidance, according to the article. University of Texas GPS expert Todd Humphreys said the case highlights wider risks from GPS jamming and the continued use of outdated cockpit GPS technology.
