The biggest casualty will be Arik Air. The big man is either going to get nabbed for his role in the power sector or the enormous airline debt which is not being serviced. Or both. Most likely both.
The most likely scenario will be the merger of Arik and Aero as they are both technically owned by the government.
Also the business jet bubble is going to burst. By the end of the year, the sector will be about 10% of its current size.
