Grey's gets LOST

[WARNING: This is the first 6 minutes of the Grey's Anatomy season finale. If you don't want to watch it.... stop reading.]

But seriously. When I heard there would be a plane crash in the finale, I, of course, thought of LOST. But this HAS to be some sort of homage. The opening scene, the music... is this for real? I always thought there should be some sort of LOST / Grey's crossover. Two gorgeous, dark-haired doctors named Shepard? That is no coincidence.
