Mick Molloy, member of the technical committee for the Outback Challenge reports that out of the 21 entrants for the Search and Rescue Challenge only 12 have made it through the Deliverable 2 stage.
Deliverable 2: Flight Readiness Review (Technical Report and Video) A technical report (Section 6.2) must be provided. The underlying objective of this report is to convince the organising committee that the team has developed a reliable and safe UAV system, along with the appropriate operating procedures.
A Video must also be supplied that includes a flight demonstration of the dropping mechanism that will deliver the payload.
A very long weekend ahead for those twelve teams as the announcement of who made it through is not made until Monday.
