Actually, Tristan, I think a year or so after that, teams had gotten to the point where they changed the challenge--they skipped the "deliver" portion and had everyone focus on the "in the building" portion. (I'd have to ask the SDSM&T UAV team's veterans to be sure of what they're doing this year.) I know SDSM&T's team was one of the mid-size choppers, dropping a quadrotor.

When SAE does the Aero Design competition, they like to adhere to the AMA safety code at least to some extent. Nothing over 55lb (without a waiver, which SAE doesn't allow in competition), no flying over pits, no metal props, nothing beyond the safety line except flight crew/event staff. AMA's safety rule is nothing outdoors closer than 25' to anybody except the pilot and helpers on the flight line. (Indoors... well, usually the indoor flyers are much lighter and much less powerful than the outdoor birds.)
