Students in Honolulu got a live look at a one-person flying vehicle, a small but real sign that personal air travel is moving from concept to demo.

• Pivotal flew its BlackFly personal aerial vehicle at Kalani High School.
• The 348-pound aircraft lifted straight up off the ground, with no runway and no helicopter rotor.
• It carries one passenger and is pitched as a personal flying machine, not an air taxi.
• No pilot's license is required to fly it.

Outlook: Expect more public demos like this as small electric aircraft makers try to build interest ahead of wider rules and sales.
