How lucky am I be on stage with fellow Grotto writer Britta Stromeyer, in a conversation that will probably include the awe that flight provokes, the physics that gets the heaviest of airliners aloft, some obscure but fascinating history, and the way flying offers perspective on grief and loss, and will meaningfully transform even those who are not pilots. You may already be a pilot or you may break into a sweat at the thought of travel plans that require passenger plane flight: this evening is for you.
