Two military aircraft collided mid-air during a training exercise at a Philippine air base, killing all four pilots on board. The incident occurred on Tuesday, according to the country’s air force. The planes were engaged in a routine training mission when they collided at a low altitude. Emergency services responded quickly but were unable to rescue the pilots.

The crash took place near a military airfield in the central region of the Philippines. Initial reports suggest the collision was not linked to any external factors such as weather or mechanical failure. The air force has launched an investigation to determine the cause of the accident. No civilians were reported injured in the incident.

This is the second such incident involving military aircraft in the Philippines this year. In March, a similar mid-air collision resulted in the deaths of three pilots. The military has since implemented additional safety protocols, but the recent crash highlights ongoing concerns about aviation safety in the country. The families of the victims have not yet commented publicly.
