1. Materials.
I will use only lightweight, non-metal parts for the nose,
body, and fins of my rocket.
2. Motors.
I will use only certified, commercially-made model rocket
motors, and will not tamper with these motors or use them for any
purposes except those recommended by the manufacturer.
3. Ignition System.
I will launch my rockets with an electrical launch
system and electrical motor igniters. My launch system will have a
safety interlock in series with the launch switch, and will use a launch
switch that returns to the "off" position when released.
4. Misfires.
If my rocket does not launch when I press the button of
my electrical launch system, I will remove the launcher's safety inter-
lock or disconnect its battery, and will wait 60 seconds after the last
launch attempt before allowing anyone to approach the rocket.
5. Launch Safety.
I will use a countdown before launch, and will
ensure that everyone is paying attention and is a safe distance of at
least 15 feet away when I launch rockets with D motors or smaller,
and 30 feet when I launch larger rockets. If I am uncertain about the
safety or stability of an untested rocket, I will check the stability be-
fore flight and will fly it only after warning spectators and clearing
them away to a safe distance.
6. Launcher.
I will launch my rocket from a launch rod, tower, or rail
that is pointed to within 30 degrees of the vertical to ensure that the
rocket flies nearly straight up, and I will use a blast deflector to pre-
vent the motor's exhaust from hitting the ground. To prevent acciden-
tal eye injury, I will place launchers so that the end of the launch rod
is above eye level or will cap the end of the rod when it is not in use.
7. Size.
My model rocket will not weigh more than 1,500 grams (53
ounces) at liftoff and will not contain more than 125 grams (4.4
ounces) of propellant or 320 N-sec (71.9 pound-seconds) of total
impulse. If my model rocket weighs more than one pound (453
grams) at liftoff or has more than four ounces (113 grams) of propel-
lant, I will check and comply with Federal Aviation Administration
regulations before flying.
8. Flight Safety.
I will not launch my rocket at targets, into clouds, or
near airplanes, and will not put any flammable or explosive payload
in my rocket.
9. Launch Site.
I will launch my rocket outdoors, in an open area at
least as large as shown in the accompanying table, and in safe
weather conditions with wind speeds no greater than 20 miles per
hour. I will ensure that there is no dry grass close to the launch pad,
and that the launch site does not present risk of grass fires.
10. Recovery System.
I will use a recovery system such as a
streamer or parachute in my rocket so that it returns safely and un-
damaged and can be flown again, and I will use only flame-resistant
or fireproof recovery system wadding in my rocket.
11. Recovery Safety.
I will not attempt to recover my rocket from
power lines, tall trees, or other dangerous places.
