Whatever a good attorney can get in settlement.

There are 50 to 60k people dying and tens of thousands more permanently maimed on the streets and highways every year. We could demand far greater safety but we choose not to because of the expense.

Are auto injuries and death more or less valuable than airline injuries and death? I'll bet that it would be cheaper to increase auto safety per passenger-mile than airliner.

We tolerate a level of probability of failure. I don't know what the stats are for airline safety vs automobile, but I wouldn't be at all surprised if airliners were 100x safer per passenger mile.
