Austin,
Great job on your leg across the Sahara to Naimey. I checked the tracking site this morning and saw that you had jumped off. When I checked again at work in mid morning I was getting worried. It looked like you were gonna go to far to the east and would miss the Niger river which would not have been good. I kept sneaking peaks and saw that you had corrected for your drift to the east. When I came back from lunch you were turning to final approach. If you felt a chill as you landed, that was me, I was your virtual lurking observer courtesy of Google earth tracking.
Ah hah! ... I knew I had that "feelin' somebody was watchin" .... good thing too ... keep me somewhat on my toes ... so thanks for that!
Jeff, I remember making that turn back to the west it was a shot in the dark ... It just felt like I was too far east.
So many little things can go wrong and make several of the legs in this event a warp into the Twilight Zone real quick.
Kevin mentioned tailwinds .... that's normally a big help ... higher groundspeed and lower fuel ... happy days!
Different situation when you are guessing at groundspeed and using a watch to measure against an average time over distance ... so you know where to turn in the absence of a landmark.
It's an educated guess, when to turn or look for a landmark from what you had documented from charts and looking at the watch.
There was an overall lack of WCA ... when ever I checked ... which meant the I was getting hit in the ol' mug or rackin' up with a nice tail wind .... didn't know how good it was until the text file printed.
More good fortune ... to back up that I was "feeling" was the great visibility at decision time .... I could actually see a much more defined river to the west ... so I cut back that way.
I didn't want to see it up close (Niger River) until way later, but it had gotten too far out of sight.
The natural landmarks at about the 2/3 or 3/4 of the distance began to form a funnel that just got tighter and tighter .... like a funnel and forces you towards where you intended to go.
Looking back now .... I don't want to make it sound too easy, but I hadn't had descent visibility I would have realized the nightmare you were anticipating .... that danger is right there .... I was lucky.
Yeah the sweet spot was east of the River .... safe way would have been to follow the river ... had third visibility been poor that's just what I would have done.
Thanks for all the encouragement guys! ...
While I've got the floor I'll recap this leg into Douala .... just completed.
Same sort of navigating for a lot of this leg even though the DR requirement was satisfied at Diori Hamani (DRRN) ... most of the nav-aids were not in ideal spots and short on range as well.
You'll be able to tell I was "chasing" a couple of them, but couldn't really "lean on" NDB's untill near the end of the flight where there are to 75 NM signals.
One just past the runway and in line with the runway and another to the west to help monitor distance to the airport by displaying relative position to the direct line in ... watch RMI needle move as you pass by.
Oh yeah ... watch out for the mountain that sits smack in a direct flight path to Douala ... if you have done a good job staying on course this thing will hurt your feelings ... I'll put up a screenshot ... I was at 8000'.
Being able to use the radios and sextant on this leg was okay, but the main thing it did was to take away the stress of not being able to use them .... still had the watch out ... oh yeah and watch out for that mountain.

Nap time for me and the crew ... hope to get back at it tomorrow.
Thanks again!
