A container expelled from the hull of a ship.
A code remnant from the very early days of EVE created a container that is vastly superior in carrying capacity than what the total hold capacity of the ship expelling the container is. This allows for a new way of interacting with the environment.
Notably: when mining in an asteroid belt it now became possible to keep mining continuously without having to interrupt the mining activity to clear out the hold in a station. This behaviour was observed by Hilmar Petturson as an unintended use of the environment, which gave rise to a fear of running out of content because mining ore now became a lot more efficient. The code was not changed because it was understood that the feature was put to a use that the designers had not intended and that this use was in fact a better way of doing things. Allowing the players to keep using this feature as they did delivered the promise of the sandbox-nature of the game and was seen as a beneficial deviation of intended game play.
