Right Supostat, or as a buddy of mine told.
The Hezballah used to sneak into a village close to the border, find a suitable length of drainpipe or whatever, place the rocket inside, point it roughly towards the Israeli border and ignite it by primitive means.
Needless to say the guys could achieve severe burns, and the rocket usually went down in some field on the other side.
But it was more than enough to call for an israeli air strike or artillery bombardment on the spot where it was launched, and that kept the fury against the Israelis warm in that village...
