Boeing shared their highlights from Day 3:

Eurocopter shared this video of their EC175 helicopter flight display:

Airbus had a few things to share as well. Like their own Day 3 highlights:

Sharklets and the A320 NEO:

Alternative fuel efforts:

And this one is interesting, IMHO. Airbus and the low-cost airline EasyJet are working together on a new sensor, dubbed AVOID, designed to allow airliners to sense and, well, avoid volcanic ash clouds. You may recall that not long ago air travel in Europe was royally snarled by a volcanic ash cloud from an Icelandic eruption. Since there is no good way to detect the actual cloud and avoid it, and volcanic ash can do serious damage to an airliner (from stripping paint to sandblasting the windscreen opaque to filling the engines with glass and shutting them down), today authorities are forced to use conservative computer models of where the ash might be and shut down large swaths of airspace. If aircraft could sense and avoid the ash on their own the impact of eruptions on air travel could be greatly reduced, as not as much airspace would need to be closed to traffic. It is still early days of course, so this may not pan out. (I do like the way the test rig has been mounted – through the window openings.)

UPDATE: Coming a little late Lockheed Martin share this video from the show with three of the F-35 test pilots describing their perspective on the aircraft:
