Capsule repla(cid:272)ed (cid:271)y (cid:858)or(cid:271)iter(cid:859: originally some discussions around jet powered glider. Cost restraints led to glider approach the space shuttle when it comes back glides and maneuvers slightly like a plane. Challenge = re-entry (certain angle so the heat is placed on the heat shield and nothing else) Thermal tiles system of tiles to withstand the heat: needed to make it reusable so they can design it to land, withstand 2500 degrees fahrenheit, Putting a plane into the atmosphere will break immediately = needed to combine space capsule + airplane. First digtionics systems historically, when you pressed/lever it was manually moving something like a gear on another gear to move something. In digital avionics, you are not manipulating the part, but instead you are telling a computer to shift the gear.
