Design

The SB-10 is a cantilever shoulder-wing monoplane with a steel-tube structure fuselage and it used the wings from the earlier SB-9 Stratus.[1] The two crew sit in tandem in an enclosed cockpit with a Plexiglas canopy, and it is fitted with dual instrumentation.[1] The landing gear is a sprung retractable monowheel with a tail bumper.[1] The wingtips are interchangeable and two types can be fitted to give a 26m or 29m span.[1] The wing center section, its main spar and wing shells of 8m length were built using carbon fiber, a first in civil aircraft structure manufacturing.

gollark: Inside-viewishly you can probably make something which nobody can think of flaws in. Outside-viewishly computer systems almost always turn out to be broken in ridiculous ways.
gollark: Unless your random number generator is ~~wrong~~ predictable somehow.
gollark: Is the standard library free of bugs? Is libc?
gollark: I mean, I'm pretty sure perfect secure simulators are *possible*, just *really impractical*.
gollark: You'd also have to be sure that all the libraries you used were fully safe and secure.
