Unfortunately there is nothing we can do to assist you. You will need to be more careful on how you drive/fly your vehicle. The admin team does not have any special "move a vehicle" ability or tool. And if we did, it would still fall into your own hands as the action of getting it stuck was normal gameplay (despite how glitchy Rust physics are, that is not something we control or configure).

A pro tip we have seen work in the past is to get someone to spawn their "sedan" type vehicle near by and try to push or crash your vehicle loose. We have seen it work numerous times. Otherwise you are just going to have to chalk it up as a loss and be more careful next time.
