FACT: A drone will not fly when inside a box.
Prove me wrong.
shareI could make a box with a wooden frame and make the sides of the box out of screen widow netting. A drone inside such a box would probably be able to fly.
It would be really difficult to find a box material which looked like the box in whatever episode you are referencing and was also porus enough for air to enable a drone inside to fly. A box material which looked solid but was porus enough would be difficult to find or create.
