(Fortune Magazine) I’m on a reporting trip in Angola, a place where the State Department advises travelers to “never touch anything that resembles a mine or unexploded ordnance.” I have brought a guidebook. It says Angola is “not a holiday destination for beginners.” I am traveling with a team of GE executives led by John Krenicki, CEO of the company’s energy unit. We’ve sat through a lecture on an especially virulent strain of malaria in the region. We’ve had two days of back-to-back meetings, visited a power station floating on a barge, and toured a liquefied natural gas plant on the banks of a tributary of the Congo River, downstream from Livingstone Falls, named for the explorer who died of dysentery. We’d had to leave behind two members of the team whose visas to Angola hadn’t come through. And now we’re in a chartered jet, homeward bound, getting ready for takeoff. A crew member comes into the cabin with an announcement. The flight will be delayed. There are wild dogs on the runway.
