The aerial flyer "Mercury"

From African Exploration and Conquest (by Robert Jewkins-ffolkes, pub. by Metheun, 1895):
"The ill-fated Explorers' Club African Expedition of 1889 was loaned the use of a small aerial flyer, owned by Lord Cowdrey, to travel from England to the Sudan. The vessel, jammed with the Expedition's equipage and members, set forth on June 16th -- delayed by Derby Week...

"Sky Galleons" crew conversion to 'real' numbers: 1 engineer, 3 stokers, 5 bridge crew (including the captain), 3 deckhands/sailors, 2 stewards/cooks, 6 to 12 passengers normally.

The Mercury is 100 feet long, with a beam of 20 feet. Her coal bunkers are sufficient for a voyage of 10,000 miles, but she must take on water every day or so (every 600 miles, actually). The ship's lower deck contains the engine room, coal bunkers, water tanks, and cargo hold (capacity 8 tons), plus the galley and crew quarters. The deckhouse contains 6 cabins for the passengers and the captain's rooms, and a very nice saloon / dining room. On the top deck is the bridge, the funnel, some ventilators, and a skylight over the saloon.
