Definitely my mum. She'd never flown before.
Moreover, I'd never carried a passenger before - this was right after my PPL, and I had only ever carried my instructor!
She was very excited for the entire five minutes while I wobbled over the valleys of Cumbria in an R22 - a big whoop as the ground fell away and a big hug after we landed.
Better still, someone was on hand with a video camera. What more could I want?
