A buddy of mine taking off from Philadelphia in a Piper Tri Pacer hit wake vortex at 300 ft and was rolled inverted, stayed with it (the roll) to complete the roll. Tower asked if everything was OK....He answered affirmative.

Another buddy on final at Chicago in clouds (IFR) hit wake in a 400 Series Cessna Twin, was rolled inverted, stayed with it completing the roll, stayed on ILS and Glide Path. Wow. Some flying!

Your friends are good pilots--or good tailgaters--only kidding. Hope with your screen name you're not flying with them!

Smaller planes are very susceptible to vortex from larger planes, and it can occur long distances away and much lower in altitude from the plane causing the vortex.

Except for those ugly brown and yellow stains and really bad smell in the cockpit, one might assume. :)
