The aircraft prototype is expected to take its first flights before the end of the year.

Five climate change pieces with something new to say: Two degrees of global warming -- the target the G8 nations last week approved as a maximum temperature rise allowable due to climate change (and which many argue is being made inevitable by slow political action in G8 nations) -- has been played in the media as a "moderate" target.
