Unfortunately this is not a good time to invest in any airline, let alone one operating ageing, fuel hungry aircraft. Even operators of modern, effecient twin engined aircraft are feeling the pain or going broke.
B744 freighters will be difficult and expensive to obtain, and may not be that much cheaper to operate at the end of the day in the lease/fuel burn/payload equation.
Sympathies to those involved, I wouldn't like to be trying to find another job in Zimbabwe at the moment or be 50 years old and out of work with an obsolete aircraft on my licence.
