A cross-cutting review of last-mile drones on efficiency, access, and sustainability. The gaps the authors themselves name — weather, flight duration, battery, an unexplained gain in access, and a tilt toward the United States — are fingerprints that later advertising prefers to wipe. This card is the citation, not a record that the full text was read through.

The abstract says the review organizes 55 interdisciplinary studies and examines possible cost savings and environmental gains. The authors also write that the literature does not explain how a drone increases the receiver's access, that weather, flight duration, and battery capacity are often omitted, and that the scene leans toward the United States while Africa and Asia are thin.

Fifty-five is the set they chose, not the number of papers in the world. A review does not transfer the assumptions of its included studies into an operating permit for a city. A sentence that access ought to increase is not a measurement that it did.
