This was really quite a useless ABC article for info. I've had to look through google news to find out: the plane belongs to Air Angola and "reportedly belongs to a group of current and former military officials". The plane took from Luanda, Angola and "U.S. officials say the airliner was last heard requesting clearance to land in the Seychelles, off the east African coast, but it never arrived" VOA adds: "Some U.S. officials suspect the plane was illegally flown off to avoid repossession. Others say it may have been crashed for insurance purposes."

iafrica says: "the plane is known to be an American registered plane and that there were no reports that it had picked up new fuel, suggesting that it had not travelled far"

I don't think it is anything to worry about--like the reports of those terrorist cargo ships full of WMD on the high seas. Fear distorts perception.
