I thought we booked a helicopter, but thankfully the pilot contacted the day before confirming an airplane. SO GLAD we flew in the plane. Much faster so we could see more sights in a sleek Cirrus (SF Bay, Oakland Colliseum, Alcatraz, Golden Gate, downtown, Half Moon Bay, Sausalito, and Presidio.). Flew right over GG!! Very comfortable and surprisingly quiet. David was a great tour guide, too. (If you do want a helicopter tour, though, make sure to contact the tour operator immediately after booking.)
