The transmitter Joshua is holding is an outdated, 72 MHz transmitter (antenna showing). It would not control the drone flying inside the aircraft. Modern drones fly using a 2.4 GHz/5.8 GHz transmitter with a smaller controller/transmitter connected to a smartphone or monitor.
This plane is a small twin propeller cargo plane. It cannot fly at an altitude of 35-40,000ft.
If it could it would be pressurized and then the external door would not be able to be opened because of the air pressure.
In the displayed information for suspect Gary Hayworth, there are two typos - "recieving stolen property" instead of "receiving", and "identitiy theft" instead of "identity".
While sampling the blood spatter in the cargo plane, the CSIs keep talking among themselves and are not even wearing face masks. High risk of contaminating the evidence with their own DNA by droplets of spit.
When inspecting the plane's cargo hold with a drone, the CSIs risk the down-wash from the props blowing lightweight pieces of evidence like fibers or lint out of the plane.
