"censor"..I guess that is the difference between someone who deals with sensors and someone that deals with censors...

Here is a image of the path I have calculated...notice how the straight the line is, even over the point where the radar spotting took place south of Spence's Bridge.

I was evaluation a report on InternetSar that pointed to a location where I couldn't see anything of interest (just like vanaj). Looking some more I saw this......and it needs more critical eyes IMO. The report is at http://internetsar.org/searches/boychuk/...ll&startr=0

I have come across one too...although it's in the old overlay and looks more like big foot (aka Vanaj).

Makes sense, but I'm wondering about one thing.... somebody earlier posted the weather for that day along the route, and it didn't seem to be the best weather to fly over those mountains. With low clouds in that area and on VFR route, wouldn't one go down that route #1 and Frazer river to be on the safe side? Would he have arrived at his destination that much later and in the dark, if he'd done that? I can't check the height of those peaks and the route down #1 in GE right now, this notebook doesn't have it installed. Just thinking out loud here....

---

The tall ones to the south of the route are ~8000ft..going down 1 would be the safer way but you are then going perpendicular to the wind and in a canyon not a good combination with those winds...I'm searching for the weather info..it might have been part of a post that was deleted..as I recall it wasn't a solid overcast and getting better but will try to find the info...

We know Ron left Revelstoke and was last seen in that area about 1430, 3 miles west of town. Based on that fact the winds aloft and the performance of the older C172 I have the following information.

With a cruise speed of 110kts and a climb speed of only 75kts and a winds aloft speed of 30-40kts depending on altitude the C172 was flying, I have come up with the following.

If you leave Revelstoke at 1430 and have an average ground speed of ~70kts(due to head winds), and fly direct to your destination on a course of 228deg, in 1 hr 43min you will be over the exact spot and time the US Border Patrol Aircraft spotted a target, at ~1615.

Now there could have been 2 planes in the same place at the same time (We call that a mid-air in Aviation) but that too would have been seen on radar, but what are the chances of 2 planes headed that same direction at the same time without meeting in the air ?

If you continue on this same course with the same average ground speed you will arrive at Qualicum Beach in 3hrs 42mins .

This would result in a landing time of 18:12 or 4 minutes past sunset with a total trip mileage of 256nm well within the range (515nm) of the older C172

Little bit of information on pilots...when they have some place to go/get to they use the most direct route and save the flight seeing for another day after all planes are not cheap to fly.

If you figure in the price of fuel, oil, insurance, hangar and routine maintenance it would cost about $110 (USD) to fly this C172.

Here is a image of the path I have calculated...notice how the straight the line is, even over the point where the radar spotting took place south of Spence's Bridge.

I have been doing these type of calculations in Aviation for 39 years (long before GPS) and teaching them for almost 24...I think I have a handle on this stuff.

Can you put that in a .kmz ?

Let me recreate it...GE Blew up shortly after doing an image save on that...give me little bit...

Also remember the strong headwinds making him later than expected and maybe worried about the weather closing in around Vancouver all this does play on a pilots mind and can cause a really bad case of "get-home-itis" and might cause him to take routes not normally taken.
