Why we need to go back to Mars
Some days ago I saw this amazing "TED talk" about sending an airplane to Mars.
About this talk:"At TEDxNASA, planetary scientist Joel Levine shows some intriguing -- and puzzling -- new discoveries about Mars: craters full of ice, traces of ancient oceans, and compelling hints at the presence, sometime in the past, of life. He makes the case for going back to Mars to find out more."

Plane with skis
I was looking for a video of a real (no R/C) aircraft whith skis and I've finally found it:
Skis :: Ohio Bush Planes from Greg Swingle on Vimeo.
Seen after a short procastinate, I'm doing my final exams...have you noticed it?
Ekranoplan
Ekranoplan from EW on Vimeo.
I've been procrastinating over vimeo and I've discovered this video. This documentary cannot finish as this video does,
I'll procrastinate a little more... :-)
