#1 Central Navigation School, Rivers, Manitoba
Our next destination was #1 Central Navigation School at Rivers, Manitoba. With the closing of Penfield Ridge, New Brunswick, Rivers was now the only advanced navigation school in Canada where celestial or astro navigation was the main course of study. It was a two day trip to rivers and we travel the CNR route through the bush and muskeg of Northern Ontario. The other recollection I have was waking up on the second morning and seeing the prairies. I don't know what I expected but you could see forever without even an anthill to obstruct the view. No wonder it was such a great place for airfields and the West was dotted with them, and with massive spaces left over. We spent a few hours in Winnipeg and I thought what a spacious, clean city - would be a nice place to live. It was May 26, a gorgeous day, and it didn't cross my mind that "winterpeg" has another side and so aptly named.
Rivers is situated about 20 miles from Brandan was little more than a hamlet. The base itself was much larger than anything we had seen thus far with Avro Ansons everywhere - they were to be our flying classroom once again. With the influx of Sergeant Observers from all over Canada the school was swamped. We were double shifted for the full four weeks and I drew the afternoon and evening shift. When we weren't flying, our school day started at 1400 hrs and ended at 2200 hrs (2.00 p.m. to 10.00 p.m.). It was no big deal, by now we could adjust to anything. It interfered with some of the guys serious drinking but others enjoyed the extra sack time in the mornings. Sometimes if we missed breakfast would go to a diner outside the main gate. The owner served a full farm breakfast for 75 cents and did a terrific business. He called the place Navigate Inn and probably made a fortune.
At Rivers we spent hours on end learning to be proficient with the sextant. We had some previous at AOS but nothing as concentrated as now. In addition to using the sextant on practice flights, we were required to take 250 star shots on the ground and plot them using the international air almanac. On several occasions we stayed up until 4.00 a.m. To complete the exercise and to find the required stars in the summer sky. We noted that the latitude and longitude of the base after every reading and to this very day I know the coordinates of Rivers to be 50 01 N and 100 18 W. So much for that but we did become very accurate at least on the ground. In the air it wasn't quite that easy but under ideal conditions we could fix our position within five miles. Astro navigation was intended to be a supplement to all the other aids, and as new technology became available we seldom resorted to the sextant on operations. More often we used Polaris, the pole star, as a general reference point to satisfy ourselves that the compass was behaving.
