有声读物: Five Weeks in a Balloon

Join three intrepid explorers as they seek to cross and explore the continent of Africa from Indian Ocean to Atlantic Ocean, except they’re doing it by hot air balloon. Scholar and scientist Samuel Ferguson, his manservant Joe, and his friend Richard “Dick” Kennedy engage in this mighty scientific feat, as they face danger after danger, enjoy adventure after adventure, and experience the literal highs and lows of Africa from the view of a hot air balloon.
