News from Jacco de Ridder:

Last sunday we had a local F2d competition in Holland
I was operating as a center circle marshal
There was a mid air collision between Fred Meijer and Bert Gijsbertsen
Both models used my shut-off
One model flew in the direction of the center of the circle, the engine still running full power.
The engine stopped at about 5 meters distance from the center.
It touched the ground 3 meters behind my back.
I never could have imagined to see the first time the shut-off was operating, from so close :-)

Kind regards,
Jacco
