I suppose we could write off all the rescue costs to Pentagon budget and local National Guard but usually the rescue groups are more local and they do have costs. Real military training, if deemed necessary should be occurring as part of a regular schedule. An actual rescue is not the time to practice. Likely the lack of practice caused the crash and luckily no one was seriously injured in the crash. But it was an expensive lesson losing the helicopter not to mention the clean up and rescue of the crew.
The question is should public pay for people's risky leisure activities. You get hurt on the mountain, you pay for the ambulance and your lift ticket paid for the ski patrol ride down the mountain. Point of bringing up the crash was what is the maximum charged? Having to pay off a Pavehawk would be a job for several lifetimes.
You pay for it already.... Hospitals charge more to cover some of the debt accumulated by people not paying, consequently the hospitals pass this onto the insurance companies who in turn, pass this on to you and every business (who in turn pass it back to you as well). Insurance is a money making industry but the costs are at a much higher level, because of uninsured people. So you already pay for it everyday in everything you buy including insurance. So you see , uninsured people actually cost you a lot of money.
