Why does Rolls Royce name their jet engines after rivers? Because a river always runs. The Rolls Royce Spey engine is what made the Gulfstream II special, and it carried on to the much more popular variant: the Gulfstream III.
The Gulfstream III, in North America, has been ruined by noise regulations. It can still fly, but it is not loud — and I love loud. The Speys are hushed and neutered with heavy and awkward looking hushkits. So, if one wants to have the real (loud) Gulfstream III experience in 2015, you are going to have to go a long way.
To have this experience, I found myself in Lanseria, South Africa. Home of Medair, as well as being a more efficient way for citizens living in Pretoria and the Northern Suburbs of Johannesburg to depart than making the long drive to O.R. Tambo International. Lanseria is not just a domestic airport, it has a full customs and immigration set up. A good thing, as I was going to take the Gulfstream up to Maun, Botswana — the heart of the Okavango Delta. Why there? Because October is the major elephant migration and it was time for me to fly VIP, 1984-style!
