- 34.1 Scope
-
Egg Lofting Duration Competition comprises six events open to single-staged model rockets that carry, as a totally enclosed
payload, one raw USDA Large hen's egg, with a mass of no less than 57 grams and no more than 63 grams; and measuring
no more than 45 millimeters in diameter. The purpose of this competition is to carry an exceedingly fragile payload for as
long a time as possible and to recover the payload without damage. The egg is intended to simulate (in miniature) an
astronaut, who must be properly cushioned and restrained to withstand the forces of acceleration and the shock of landing.
No material may be affixed to the egg (e.g., glue or tape).
- 34.2 Eggs
-
The Safety Check Officer or other official shall provide the egg to each contestant presenting his/her entry for pre-launch
safety check. Each egg shall be numbered, and that number shall be recorded on the contestant's flight card. A contestant
shall not be required to use an egg that has been previously flown by another contestant.
- 34.3 Return
-
Following the flight, the contestant shall present his/her entry as recovered and, in the presence of an official, shall remove
the egg. The official shall determine the extent of damage to the egg. If the official cannot examine the egg, the entry will be
disqualified. If the contestant removes the egg in the absence of officials, or breaks the egg in the process of removing it
from the model, the entry shall be disqualified. If the shell of the egg is broken or cracked, the entry shall be disqualified.
Any model that cannot be returned to the officials shall be disqualified. Rule 10.4 does not apply. All entries must comply
with Rule 16.7 (no catching of models is allowed for official flights).
