Yesterday, San Diego residents were treated to an unexpected sight as two military jets gracefully traversed the city’s skies. This isn’t exactly a common occurrence in the Miramar neighborhood, and one lucky individual managed to capture the awe-inspiring spectacle on camera.

The two F-15 Eagle jets, estimated to cost around $80 million each, were spotted soaring over the cityscape, leaving a trail of astonishment in their wake. Their impressive speed and maneuverability were not the only things that turned heads; their powerful engines also produced a thunderous roar that echoed through the streets below.

The footage of the aerial display was originally shared on Reddit, where the user who posted it expressed curiosity about the jets’ presence in San Diego. Here, one user claimed that it was part of a yearly winter exercise that took part above the city.

The San Diego Winter Fury military exercise is an annual training event held by the United States military and is designed to improve the skills and readiness of service members in a variety of areas, including combat operations, humanitarian assistance, and disaster relief.

The exercise typically involves troops from all branches of the military, including the Army, Navy, Air Force, Marine Corps, and Coast Guard. The training scenarios may include simulated combat missions, humanitarian aid operations, and natural disaster response drills.
