Static line towing with two stage release. You can see here two
ordinary releases. The first one is Russian Mouth Release (RMR), the second one
is barrel type release. So, pilot is taking off with RMR and after reaching
about 150-200 meters he is connecting second release with the bridle below the
speed bar to the ring in the end of line using ordinary carabineer. Of course he
is immediately releasing RMR and continuing towing with barrel release.
