EB was deposed circa 5 years ago during the Karlene Pettit trial. Was surprising the things he did not know. Did not know what ICAO was. The transcripts of his, Grahams and Dicksons are all on the internet somewhere, I've read them. Makes for interesting reading.
Maybe it doesn't matter that he doesn't really know aviation lingo. He's a financial guy, and granted he makes us lotsa money. Plenty of others to handle the "flying stuff" I suppose.
