Okay. Let's go to the fixed-wing search and rescue procurement that I understand is currently in the works. It hasn't been finalized.
What has been brought to our attention is that there was an SOR version two in April 2005 and then an SOR version four in July 2006. Because we're trying to understand the procurement process, how is it that one jumps from one set of requirements to the next? I think in this case one of the examples was the 6-foot 11-inch cockpit height. So what is it that takes place in between one version and the next version?
