I've found that all it usually takes to draw out an engineer is to ask a couple of technical questions and then remain calm while listening to the answers. Most people tend to take on a blank, frightened look as soon as they realize that a technical explanation is under way; if you can resist giving this reaction and simply listen, your engineer will open up and tell you everything you ever wanted to know.
