The spacecraft, which consists of a reusable space capsule and an expendable trunk module, has two variants: the 4-person Crew Dragon and Cargo Dragon, a replacement for the Dragon 1 cargo capsule. The spacecraft launches atop a Falcon 9 Block 5 rocket, and the capsule returns to Earth through splashdown .
This model incorporates many revisions to the basic Challenger design, including a larger and re-shaped vertical fin, fiberglass wing tips and redesigned landing gear. Qualifies as a US Light sport aircraft, 110 reported completed and flown by the fall of 2011. [1] [8] [11] Challenger II LSS XL-65 Two seats in tandem, 29 ft (8.8 m).
The Fitchburg engine (illus.) [ii] was one of a series of similar engines offered in various configurations.The steeple arrangement required a high ceiling to the engine house, but had two advantages: [6] it took up less floor space than a horizontal engine and it also required less complex masonry foundations beneath the engine.

William Roberts horizontal tandem compound engine - 'Peace'. Marshall undertype steam engine. There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft.
Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.
Dragon Challenge operated with several steel and fiberglass trains. Each train had eight cars with four seats for a total of 32 riders per train.
