Flying out of sight only underlines the illegality of the act. In Germany you need to keep relatively near to your drone and technically need to be able to fly by sight only (so can’t stand in a building/car and then not see your drone).

Spot on. For this, only the bottle cap production changed, the bottling process for beverages hadn’t to be touched at all.

Additionally, the new caps use less materials, so they also save the company money.
