Ghost Freight - Douglas J. Lindsey

He spotted a 2,000-pound ghost, and the sky turned against him.
After four decades balancing manifests for Atlas Skies International, logistics officer Ken "Kenny" Smith trusts numbers more than people. When a routine Dallas-to-Munich cargo run shows a weight that shouldn't exist-and the digital record rewrites itself-Kenny digs in. Every time he gets close, the data shifts, co-workers vanish, and his own pension freezes overnight.

With only a rookie cybersecurity analyst and a skeptical Federal Aviation Administration investigator at his side, Kenny tracks a trail of phantom flights moving contraband drones to a desert strip. The proof is locked inside one last "ghost" run streaking through a moonless sky. Fail, and the next manifest erased will be his own.
