Welcome to the South Atlantic. One of the most inhospitable places on Earth.  We visit some stunning landscapes. This trip takes us through the remote and uninhabited South Sandwich islands. Not to be confused with the Sandwich islands which we now know as Hawaiʻi. This is an archipelago of fire and ice. This is truly an adventure. We hop from island to island starting at Thule named after the mythical land of Thule, said by ancient geographers to lie at the extreme end of the Earth. We end our trip after a tour of the island of South Georgia made famous by the epic journey of Ernest Shackleton after the disastrous attempt to cross Antarctica on foot in 1916. The voyage was on the James Caird a 22.5-foot (6.9 m) whaleboat. It was a journey of 1,300 kilometres (800 mi) from Elephant Island off the coast of Antarctica, through the Southern Ocean to South Georgia. We will follow parts of his final route over the island.

Autopilot in Nav Mode is useful. Speakers on, as you will hear the captain sharing information about interesting sights as we pass. Pop out the MFD as a separate window to show the Map (Right Alt and LM click). This will help navigate when approaching waypoints. Try to stay as close as you can to the pink course line on the Map/compass. If you think you have missed some commentary, go around and refly that part of the route.
I have enabled Weather and ATC. However ATC may interfere with the commentary so only switch it on if you are ok with that. If it does become a problem you can either switch it off or go around to refly that section of the route. You can change the weather, maybe to experience a South Atlantic storm.
I have avoided using apostrophes in the Narration as MSFS Text Reading doesn't seem to handle them well - Apologies to grammarians. 
The Narration subtitles starts with "Missing Audio" Please ignore it.
If you get a warning notice that Microsoft Azure Text to Speech services are unavailable, it may be a temporary loss of connection. Try going round and fly that section of the route again to trigger the commentary.
If you crash your aircraft and restart that leg, the flight recommences at your crash location, which isn't good when over the sea or in trees. I recommend, when completing a leg, you take a copy of the save file in 
*:\Users\*\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\MISSIONS\ACTIVITIES
You can then restart from the start of that leg rather than going back to a previous leg.

The flight is 694nm long and has 9 Legs. We use the Beechcraft King Air to get us over the sea passages quickly.

Installation:
Unpack the included folder from the package into the community folder. Restart the simulator.

Add-ons:
I recommend using MSFS 2020 Google Map replacement (https://flightsim.to/file/19345/msfs-2020-google-map-replacement) by derekhe as it enhances the scenery. MSFS puts trees in weird places eg on glaciers. Bing photogrammetry is also somewhat sporadic in its coverage. This mod does seem to remove some of the anomalies however some colours may not be correct. The Google logo also appears in some places. There is also some pixelating of the photogrammetry in some areas but overall it is worth using it if your bandwidth allows. (I ignored the warnings re lack of bandwidth).
