Now, seeing as how there is a new stealth design for jets, commercial and military, we might need new parts for the $#@!pit interfacing with the engines and wings? This would be where we replace the binary motherboards with analogue parts that are more reliable and do not jam, of course.

So, how would we 'ignite the engine?' We could use conventional engine parts and mechanisms for this. To lift off? we would need to gather speed and use the wings through conventional mechanisms to lift or reduce the flaps on the wings, or, directly to the engines, of course. Then there is the option of harrier taking off mechanisms, with the engines lifting the jet from the ground with lesser engines, also used for reducing or increasing space occupied by the jet. Optionally, we could replace the whole wing stick or make it interface with a lot of minor engines, that would reduce the pressure on the flaps and then allow for better more sensitive mechanisms - more complicated mind you - for steering.

Then, we could use a conventional 'space shuttle rocket breakaway mechanism.' This would be the circle that goes around the break away module of the space ships to push the debris from the main part of the rocket, dropping excess weight. This mechanism could be like a circle that pushes in a sphere to grant speed and direction, of course.
