[Squawk 8888]

I thought most planes have a back up indicator that isn't powered by pumps.

Most planes only have one set of instruments, but larger ones have two sets with separate power sources. There is a bit of redundancy, though- most aircraft use a vacuum pump to drive the attitude and heading indicators and electric power for the turn co-ordinator. I don't know the FAA standards but in Canada even VFR pilots are required to train for instrument flight without the attitude indicator; it's exhausting but not impossible. My own take is that unless there was a compelling reason (such as low fuel) to make that approach he should have flown to some alternate airport where visibility was better.

If I remember right, he had just taken off from the airport. Right into a severe storm !! They were trying to make a fundraiser. I recall when they announced this on the TV, I thought what fool would be out flying in this weather. ( I live in St.Louis ).
