Never again..   

Sure. I was ferrying a 407 from Galveston to Lake Charles via KGLS → V70 → WOLDE → SBI → MARSA → LCH → KCWF. Weather was MVFR, I’m at 2500ft. Directly over SBI I heard, AND FELT the loudest explosion, followed by a very bright green flash, like you see when a transformer blows.  Suddenly all of my instruments failed, panel lights were flickering, and music from what I think was 1940’s was playing through the Bose. I had been talking to Houston Center but had no joy in even trying to get the radios to work. I was wanting to see about making a precautionary landing in Sabine Pass, but I couldn’t see anything and I couldn’t talk to anyone. All aircraft operations were otherwise normal, and alas, she kept flying. I actually pulled out the flash light and VFR sectional to see if I could make sense of where I was, but again, I had zero visibility. The entire event occurred over a span of about 2-3 minutes, after which the panel lit back up, and all instruments began functioning again. About that time I heard Houston Center calling me saying they had been trying to hand me off. It’s a good thing I used the bathroom before departure.
