Red carpet in D'jamena, the president is going to fly
I flew for 2 months around Chad and i saw and suffered the presidencial aircraft. Everytime the president flies they close the airport one hour before the etd. And I remember in Abeche (one of the two paved rwy in that country) there was a Hercules C130 crashed 100 yards before the rwy (maybe you can still see this in Google maps ) and the locals said that was in a night app without rwy lights. I think the only Hercules they had lasted 5 or 6 months.
With all this, I'm saying that Chad is Africa and Africa has nothing to do with the rest of the world. Everytime you fly throug this continent ( except for Maroc, South Africa and not much more) is an adventure.
Regards from Spain and fly safe
