Ok, so the main body of the airship was completed (complete with carpenter's blocks).
I had not added on the balloons yet.
So I then added the helm to the front of the ship. With the gauges in hand (im assuming they were the proper ones for the airship, as there are two versions). I misclicked and ended up right clicking the helm to jump into the driver's seat, it was then that the game crashed and kept crashing as I tried to log in.
I did try repeatedly hitting the left shift to dismount but to no avail. I tried also disabling my resource pack (sphax resource pack) and it didn't work still.
Fortunately one of my friends is also on the server. He tried to destroy the ship, but could not. So he poured lava on it, lol.. I'm not sure what he did but it worked and he was able to remove the helm from the ship. I was then able to safely log in with no trouble.
I'm going to try rebuilding the ship later this day.
