Coloured engraving by W E Earl showing the Nasau balloon, carrying the English aeronaut Charles Green (1785-1870) and six other pasengers, ascending from Norwich, Norfolk on Thursday 24 September, 1840. Green used this coal gas-filled balloon for his most famous flight from London to Nasau in Germany in 1836. It was on this voyage, along with pasengers Robert Holland MP and Thomas Monck Mason, that Green succesfully completed the world's longest flight, covering an estimated 480 miles (770 km) in 18 hours. By 1840 the balloon was a regular showpiece giving public flights in pleasure gardens.
