Show the payload being released and falling toward a clearly marked landing zone. Include visual labels: UAV, payload carrier, mechanical release, inert training payload, drop trajectory, and designated landing zone. Professional UAV engineering/test environment, clean technical presentation, realistic proportions, daylight. The payload must be completely non-explosive and non-pyrotechnic. show crackers, smoke bombs, explosives, e-matches, ignition systems, flames, blast effects, or weaponization.”
