LTA/balloon vessel a.k.a. "Dolphin", becoming a parachute if burst, envisioned as bird- or fish-shaped rather than round (like standard balloons of the time).

  • "a figure or form, whose farthest extremities may be in an horizontal and longitudinal direction, or nearly so, such as the shape of a fish or bird"
  • "The fins, feathers, or fans, are made of silk, or any other light stuff or substance capable of acting upon and retaining the air, fixed to a rod or staff, by means of small ribs of whalebone, or any other pliable or elastic substance, placed into the rod or staff, on one side only, like a feather, one side whereof has been stripped of its plumage." About five of these are placed on each side, to form wings
  • "As a further additional means for he guidance and direction of our balloon, we have invented a moveable weight, which will also serve for ballast as occasion may require. This weight consists of a barrel containing water in quantity more or less as may be thought necessary, according to the size of the balloon, provided with a cock, and suspended by ropes or straps which pass over pullies from the gondola, boat, or car, to the end or tail of the balloon, in an inclined direction.

Means of navigation include moving the wings, moving the rudder, shifting a weight built into the vessel, and, for vertical motion, releasing ballast or balloon air.
