I just came across an interesting article at: http://www.canada.com/victoriatimescolonist/news/story.html?id=77ec86f2-c47a-4964-b52d-57b0c2be7d43

It is about how a parts shortage has been grounding Canadian Air Force Cormorant EH-101 helicopters, which are used for search and rescue missions. The article mentions the Ron Boychuk search in passing.
