Does anyone else still use a Speed Wrench Driver?

I have removed thousands of sheet metal screws, (and replaced them) in the aircraft I worked on in the USAF in England and France. You didn't have power on the flight line back in 1960 for drills, and battery drills weren't available then.

They still do not allow the use of electric screwdrivers on aircraft that I am aware of......... To easy to strip a screwhead out. The panels on the aircraft with all the screws are high stress panels and that is the reason for screws not dzus fittings. Have turned more screws with a speed handle than I care to think about.
 
The only speed wrench I used with used with sockets and resembles a crank. With use comes skill of operation and one could easily spin nuts down by using a rotating force on the crank part which would drive the nut down, quick tighten in place and then come back to tighten to torque after they are all done. If you were going to leave the shop we always marked the nuts torqued with a white marker, in case someone else came on the job. It helped to remember what you were doing as well.
