Operation Tripwire Leg 1

Leg 1 — KDMA → L92 Davis-Monthan AFB → Alamo Landing Field Tucson, Arizona → Alamo Lake, Arizona

Davis-Monthan Air Force Base has long stood as one of the most strategically important military installations in the American Southwest. Home to surveillance aircraft, electronic warfare squadrons, and the famous aircraft boneyard, it serves as the perfect launch point for Operation Tripwire.

Alamo Landing Field sits isolated beside the harsh desert waters of Alamo Lake, surrounded by rocky ridgelines and empty wilderness where smugglers have moved contraband for generations.

The Quiet Sectors

The operation begins beneath an amber desert sunrise. Your King Air lifts from Tucson carrying a surveillance crew assigned to monitor Sector One — a stretch of remote desert historically used for cartel movement during moonless nights.

At first, everything feels routine.

Border Patrol trucks crawl slowly across dirt roads below while isolated ranches sit motionless beneath the rising heat. The mountains cast enormous shadows across dry riverbeds that have served as smuggling routes for decades. Intelligence briefings mention increased cartel activity in Sonora, but command insists the situation remains contained.

Then your radar operator notices something strange.

A transponder return appears briefly twenty miles south of the border at extremely low altitude before vanishing completely behind mountainous terrain.

No flight plan.

No identification.

No radar response.

Ground control dismisses it as atmospheric clutter.

But inside the cockpit, nobody believes that explanation.
