She’s a brilliant aerospace engineer who’s also a cougar, sort of a brainy British Susan Sarandon. She gets involved with a 20-something from Algeria. Did I mention he’s Muslim? Did I mention she works on defense projects? You don’t need to be an engineer to do the kind of math that’s going on in “Flying Blind” (2013). So, is this dude a terrorist or are we just paranoid bigots? Is there even a shred of romance to their relationship or is she just a slut? Is everything as black and white as these questions? Or grey as the Bristol sky?
