Steve's Video Of The Day: "V-22 Osprey"

I love the V-22 "Osprey". A V/STOL machine that can insert and retrieve troops from small clearings, and then fly at high speeds. A transport and helicopter, in one. Tilt-rotor and tilt-wing technology has slowly evolved, and Canada had a very promising entry in the field in the Canadair CL-84 Dynavert. Very cutting-edge, but like any Canadian military aviation project, it was headed for the scrap heap. (Remember the Avro Arrow? Anyways, lets see the V-22 Osprey, and some of it's predecessors.)

The actual link to see the details of this video, which is available for download or on DVD, is here: . I'd appreciate if you'd please remove the direct link to the video file and replace it with this one. Kind regards, Craig (Producer of the film).
 
Sorry about the corrupted code in that first comment. Not sure why it duplicated my user name. And I only hotlinked a small bit of text. Strange. Maybe it is a blogger-anti-comment spam tool? I've tried again: Sorry for the mess!
Here is 2nd try: .
 
I changed the link, hopefully to the right one. If not, or if so, let me know either way!

Cheers!

Steve
 
Do you think the V-22 could be used for commercial purposes ? Like an inter-city transport or for short to medium range logistics.
 
A V-22 type vehicle would be outstanding for inter-city and short-range locations. Able to use short runways, take-off and land vertically if necessary, and retain the speed. Alas, nowadays, the "barriers" to developing new technology are often insurmountable due to financial burdens and regulatory requirements.
