Yes! Absolutely. In fact so much so that once he gets up higher his terminal speed will exceed the speed of sound. And as you suggest the speed will continue to decrease down to the more pedestrian 120MPH near his landing/splatter* location.

* In this case the splatter will be confined to the inside of the special splatter bag. This will allow easy no-fuss cleanup.

Or. A unique speed-up if he is intercepted by a Pratt and Whitney somewhere.
