"Nigeria used to have Okada Airlines, operating the world's largest fleet of BAC1-11s."
I once saw an Okada Air 1-11 at Dan Air maintenance and it was in such a state - broken seats, oil leaking out of every pore, tires different sizes, huge curls of paint sticking up from aerofoil surfaces etc - I thought it was being scrapped; but no it was in for a C check!
