That's very true.  

Long ago there was an article in QST...might
have been by/for KH6IJ, about his method to control that spin....IIRC, he
attached a cord to the brake latch and the other end to a brick.
The idea was that if he lost control of the handle when cranking
the tower "down", he would drop the brick to set the brake latch.

I adopted that method except that I use a spring to normally
keep the latched engaged, then attach a cord to the latch
itself and pull it in order to un-latch the latch when I need
to.

I'm not saying either method is perfect, but that's what I
do when I'm tilting over my old EZ-way 50-footer.  So far,
so good.
