Pet peeves of mine, using the term IT and "software developer" interchangeably. Big hint for you, just like you'll never hear an MD say they're "a medical professional" instead of simply saying they're a doctor you'll never hear a software developer refer to themselves as an "IT guy". IT guys are valuable and some are quite good at what they do. Very few passed up an opportunity to be software developers and opted to do "IT" instead because it was more intellectually rigorous, higher paying, and more interesting, for example. Generally if you're into computers and can code you do, otherwise you do "IT" (or like me start a company and hire developers!).
So no, an IT guy would know fuck all about the guts of the software used to put the flight schedules up on the departure monitors in the airport, let alone anything about embedded software, let along anything about the QA and test routines of embedded software used in aircraft. And to top it all off he doesn't even know enough to know that Boeing has a design philosophy that means pilots can always fly through controls to the point of damaging or destroying the aircraft while Airbus has the opposite philosophy, so if you're going to be at all credible you would have picked Airbus instead of Boeing!
