I'd be delighted - by static tow, I mean towing by winch & by power tow I mean being towed by another aircraft, I suppose more usually called an aero tow.
Lockout is the phenomenon whereby deviation from the course of the tow line causes the pilot to be unable to counter the turn away from the tow direction due to the tow line tension, resulting in rapid downplaning and usually a disastrous outcome. It's normally a deviation left or right from the tow line, but there have been lockouts where the towed glider overflys the tug aircraft & downplanes as the tow line tension causes the bar to be pulled in. Pretty rare though.
Here's a near lockout example:
