While not SAR, the local air ambulance service is expensive. I know a pilot for careflight. He told me it is about $500.00 per hour just to operate the helo. That doesn't include any pilots, nurses or supplies. They have a membership program that is like $145.00 for 5 years for a whole family.

If they are called to get you, it is $10,000.00 when they go light on the wheels. From there on, the sky is the limit (pun not intended).

Seems like $145.00 is pretty cheap to me.
