Hmm - our management won't let us use Lego to fix the aircraft anymore.
Same route really, large pile of Lego as a youngster. Toyed with the idea of an industrial technology degree (robots and the like) until I lost interest in school and they lost interest in me and suggested I leave.
Ended up fixing photocopiers for a year 'til I got made redundant so joined the Air Force, recruiter asked me what I'd been doing, when he heard fixing photocopiers, he pointed me in the dirtection of avionics.
