Well, I spent quite a bit of time there in Nigeria, looking at the aviation scene from the inside out, when I do not share your optimism.
Why, I even had my Cessna 402 christened by Maryam Babangida one hot, bumpy afternoon, just before landing at Minna Airstrip, when I then had to find a rag and a bucket full of water to get it back to its previous state. How's that for being some sort of aviation insider?
We should now see a period of "rooting out corruption," meaning "Okay, you lot! You had your turn at the trough, but now it's our turn," followed by "business as usual." That's my guess, but, hey, pigs could fly, so that your sunny vision of a complete change of tack might be right. Give it a year or two and then we can see who's got it right this time.
