My first AD&D campaign was in a slighty adjusted Mystara, where our party managed to capture a Venyan airship on their way to Alphatia...
My character posessed the engineering and other skills necessary to fly it, and all, and through a series of lucky rolls and ad hoc house rules (the 'God Call'), got it to Alphatia, where we had all sorts of fun before my character decided to rebuild is as a more potent ship.
Five years and nearly a million gold later, it's done, and quite a ship. Taking it for it's maiden flight, there is a serious problem... For no apparent reason, the strange device Xeriar (my character, duh
used to control the ship got red hot, and the magics that powered the ship failed.
Depressed and anxious, Xeriar exits the vessal, going over it to survey the damage and try to figure out what is wrong. After a moment, a voice from the ship is heard "Stop that, it tickles..."
What followed was the most intense roleplaying session I'd been in before or since (I'd played D&D, TFT and some others before), but the kicker was after he had first befriended the ship (he really couldn't call it his anymore...)
On their first flight together, they encountered a few more of the Venyan ships that Starchild (IIRC that's what I named it... It decided to be a 'she' later
was rebuilt out of. It hadn't known combat before, so it screamed when they shot at it (It wanted to be friends with them, too).
It gave my character control of the ship ('It' was more than just the ship...) then, so Xeriar took the ship to a higher altitude than they could attain...
"But... I want to talk to them."
"They can't talk... They don't... They aren't sentient..."
"But they move..."
"They move at the control of those on board them, they don't decide..."
"But I want to talk to another like me."
"There are no others like you, I could not make another like you..."
"You mean I'm alone."

Sadness :-( Eventually we ran into a powerful Gold Dragon that helped 'her' find more of 'herself'... But the campaign ended shortly after. :-(
