This screen displays a radar view of the Lower Mainland airspace, including CZBB (Boundary Bay airport), CYVR (Vancouver International Airport), and CYNJ (Langley Regional Airport). CZBB’s runways are visible just above the pen and to the left of the white arrow pointer. The yellow dots with lines just above the CZBB runways are two aircraft on downwind for runway 07. You can also see a couple of aircraft at CYVR. Taken from CZBB’s control tower on Jan 28, 2012.
