Two manned multirotor helicopter-like flights -- Kitty Hawk Flyer seen in San Francisco:
Multi-rotor aircraft are related to those "Drone" devices making all those fantastic aerial movies. Except, they use quite a few more motors and propellers, and in some cases they carry passengers. Electric manned flight is happening, and it may happen faster than we expect.
We have two aircraft to report on today. The first, the Kitty Hawk Flyer, got a lot of overly hyped attention back in April. In this video we see one flying not in the overly scripted scenario of their advertising footage, but along the San Francisco waterfront.

The second is a gentleman with a german accent flying a vehicle in a forest, presumably on his own property. He recently posted a video showing the first flight of his multi-rotor design, and today's video shows a tuning test-flight. He flew for 11 minutes achieving 80% depth of discharge, indicating more flight time than the previous video. For previous coverage see Very cool Manned multirotor helicopter-like -First Flight!

First test flight with this aircraft - 8 minutes of flying time consumed 57% of the battery capacity. The power comes from a 35 kG LIPO battery pack, and it's estimated to have 14 minutes total flying time or 11 minutes to 80% depth of discharge. He's not wearing a helmet to feel the freedom thing.
It kicks up quite a bit of "wind" while flying - notice what happens to the plants.
Since this is an initial test flight, he's taking it easy ("don't fly higher than you want to fall"). Certain control system limits were set conservatively and he may loosen those limits for future flights.
