Fasten your seat belts, Grey's fans -- it's going to be one hell of a bumpy ride!

Grey's Anatomy is bringing the medical dramz to a whole other level in next week's season eight finale episode!!!

The Seattle Grace doctors are forced to face a life-threatening situation when...dun dun dun...their plane crashes!!

Hmm...this sounds all too familiar, no? LOLz.

Check out the promo for the finale episode, Flight (above)!!!

The show STILL has renewed for a ninth season, but as we reported yesterday, six cast members have already signed on for two more years.

We're guessing that must mean whoever gets killed off won't be Meredith, Derek, Cristina, Alex, Richard or Miranda...so Lexie??? Maybe Arizona?!?

Although, it COULD be one of the six we mentioned and maybe they'll come back as a ghost, ala Denny!

Oh man, even though the plot isn't that creative, we are STILL going to tune in on Thursday to find out who doesn't make it!!!
