After Tallinn, teams would either take the ferry to Helsinki, Finland for a full leg (unlike the 1/2 leg in TAR10) or fly to somewhere else in Europe or to North/West Africa. I researched flights between Tallinn and two approiate cities in Africa on Lufthansa via Frankfurt. (both flights departing August 4, in Estonia)
-Possibility 1: to Algiers, Algeria (LH3179/LH4122) departs 6:50pm, arrives 12:00pm on August 5
-Possibility 2: to Accra, Ghana (LH3179/LH566) departs 6:50pm. arrives 3:25pm on August 5
-Other Possible legs after Tallinn: Czech Republic, Germany, Latvia, Russia, and Slovakia.
