two neat pictures

First from Chris Jordan who I've mentioned before. Not all of his new work turns my crank, but this one is pretty neat (go here for a slightly bigger view).

Partial zoom:

Detail at actual size:

Jet Trails 2007 Depicts 11,000 jet trails, equal to the number of commercial flights in the US every eight hours.

There's also an interview with Chris on PBS here

And sticking with the airliner theme the second picture is from the Guardian - Engineer's Concorde prototypes - part of an auction of all sorts of design bits and pieces and sapre parts from Concorde up for auction in Toulouse if you want to go and bid...:

Concorde, that most charismatic of all civil airliners, always did look like a paper plane. Not just any old school playground paper dart, of course, but the most beautifully thought out and most aerodynamic aircraft possible, folded by the hands of brilliant, if still unsung, backbench aero-engineers.

Now we learn that Concorde engineers really did make paper aircraft at their drawing boards and workbenches, testing these outside the former British Aircraft Corporation workshops near Bristol during their lunch hours. Made of any scrap of paper or card available, these primitive, hand-propelled Concordes did their bit in the design process of the most famous, and dynamic, airliner of all.
