Egg Lofting Duration

« Duration Competition
37.1 Scope
Egg Lofting Duration comprises six events open to single-stage model rockets that carry, as a totally enclosed payload, one raw egg intended to simulate carrying an astronaut. The purpose of this competition is to achieve the longest flight duration and recover the payload without damage.
37.2 Eggs
Eggs must be raw and have a mass of not less than 57 grams and not more than 63 grams; and measuring no more than 45 millimeters in diameter. Prior to flight each egg must be uniquely marked and the mark must be recorded on the competitor’s flight card. A competitor shall not be required to use an egg that has been previously lofted by another competitor. No material may be affixed to the egg (e.g., glue or tape).
37.3 Return
Following the flight, the competitor must present his/her entry as recovered and, in the presence of an official, must remove the egg. If the shell of the egg is broken or cracked, the entry must be disqualified. If an official cannot examine the egg, or the competitor removes the egg in the absence of officials, or breaks the egg in the process of removing it, the entry must be disqualified. If an official cannot examine the egg, the entry will be disqualified. Any entry that is caught or cushioned prior to landing must be disqualified. Rule 10.4 – Return of Inaccessible Models does not apply.
