I'll get a couple of things off my chest on this topic which I have pretty good experience of.
1. CHC even in this market were likely making plenty of money in EG, it was a monopoly in a market with very high barriers to entry and no mean amount of risk. They're also flying S76C series which are hardly expensive to run in this market. Most of the ac they had in EG were owned anyway.
2. If this comes to pass, I'd put money that the CHC management in charge of it (not base staff, in the offices abroad) knew this months in advance, were warned, ignored it as 'same old Africa', did nothing and the authorities pulled the plug.
The base staff have been superb. The fault for this if it comes to pass is elsewhere.
