A captures pulsejet on a stand. Notice that is operating by being fed
air, fuel, and notice the spark plug lead.
Again, notice how the pulsejet CANNOT operate INDEPENDENTLY without
flying at at least 186 mph.

Note that, despite what your subject heading might say, this is not a
captured V1 pulsejet being fired. It is actually a replica built by
Survival Research Laboratories. (the page from which the image you
referenced was taken is at :
http://www.texasmonthly.com/ranch/srl/v1.php and more detail on the
SRL's V1 project can be found at http://www.srl.org/machines/v1/

Note that SRL have a number of pulsejets in their inventory, and they
all operate without forced air -- a fact that can be testified to by
the thousands of people who have watched their shows.

And don't tell the millions of people who watched me build/drive a
pulsejet powered gokart on Junkyard Wars last year. I wasn't doing
186mph -- but that pulsejet engine was certainly running strong and
loud without a hint of forced air (except briefly just to get it
firing)

And if you check out this page:
http://aardvark.co.nz/pjet/lhkart.shtml you'll see that I know I was
only going 57mph because I had a GPS system onboard to measure the
speed.

Check the brief video clip at:

You can also see a pulsejet running without forced air on a test stand
in this clip (Real Player required):

So, either I'm achieving the impossible, or I am right when I say that
pulsejets can and do create static thrust and don't need to be moving
through the air at any speed in order to work.
