Something you can't do in GTA4, but can in SR2.

I hijacked a Gulfstream, heading towards downtown.  Right as I was over my base, I jumped out of the cockpit.  Now normally you can initiate a hang gliding minigame, but, since the left side of the plane had dipped down a bit, my character got clipped by the wing and she went plummeting (screaming the whole time) towards the streets below.  Where she landed on a van.

FUCKING SWEET!
