Cargo storage on NPC bases

[Crazyr0m]

What use would this be?? Could be helpful if you could enlighten us

There are many uses.
Example 1: you are flying in your 5ker hauling some ore, you pass near a friendly POB and see its losing HP. You can land on an NPC base nearby, STORE YOUR ORE, make some trips with FOW and RA to the dying POB, then recover your ore and continue your trip.
Example 2: you have some important item you can not lose, maybe some permit or docking access, illegal goods permit, etc. You might leave it lying on a base to avoid losing it, if you are not going to need it in current trip.
