The vortices generated by lift in the departing aircraft aren't the
only form of wake turbulence. When I was based at a class B, I had
numerous problems flying through the churned air generated by the
engines of a departing jet (DC-9s and 727s were the worst). If
spacing is tight behind a departing jet, it would not be unusual to
experience some pitch and roll excursions in the flare.

Heck, I used to get some exciting moments in my Cessna 120
on *taxiways* behind TWA Super Constellations.
