Narrative:

I had just departed south county airport runway 14 and was in a climbing right turn (15 degree bank) heading 220 degrees when a twin engine corporate type jet heading about 330 degrees suddenly appeared in front of me in a hard left turn. Once passed me he leveled his wings and continued on a descending heading of about 330 degrees estimated speed over 200 KTS, my speed 90 KTS . I had just departed south county unicom 122.7 and was switching to bay approach 120.1 for an ILS to sjc.
