Following are our selected clips with content description underneath.

At about 8 p.m. on Tuesday Jan. 31, Cpl. Kimball Vardy RCMP Makkovik Detachment calls Capt. Kristin MacDonald of JRCC Halifax to learn the status of the Canadian Forces Griffon helicopter. The aircraft is en route from CFB Goose Bay. This more than 48 hours after Burton Winters was reported missing.

During the conversation, Cpl. Vardy reveals NL Fire and Emergency services was contacted by the RCMP the first night Burton Winters was reported missing (Sunday January 29th), and were told to call back the next day for air support. This contradicts earlier reports that Fire and Emergency Services was initially contacted Monday. The first voice is that of Capt. MacDonald.

At about 8:25 p.m. on Tuesday, Jan. 31, Capt. Kristin MacDonald of JRCC Halifax calls NL Fire and Emergency and urges them to have aircraft ready to search first light Wednesday. He also suggests FES uses "air spotters" who are military-trained civilians. They're known as CASARA (Civilian Air Search and Rescue Association). The FES person on the phone appears to have never heard of the group.
