I had the same experience probably at the same age on a night flight somewhere above Europe. I don't think I will ever forget the stunning look of that fully illuminated cockpit with what I assumed to be one million buttons and screens scattered all over the place.
My first visit to a cockpit was also at night, on a Vickers Viscount - I think it was on a trip from Cooma to Melbourne, and I was about 9 y.o. at the time.
Like maehhh, I never forgot the experience.
