Thanks for that Groundbased. I found the FSF website but didn't register as I thought it would either cost money or require me to demonstrate my qualifications, or both. I didn't particularly want to have to give out any personal type info on a website, so I shyed away from registering.
I've taken your advice and registered and also found and downloaded the article on Erroneous ILS. Thanks very much for that.
My previous search found a reference to Erroneous GP on the Boeing site, but it was impossible to identify which specific article it was from the ones they listed. I couldn't afford to stay online long enough to check thru them all.
But, thanks to you, it looks like I've got the information I was primarily looking for. I'll keep an eye out for the official report, though I don't know which mob would've handled the investigation... maybe that'll be made clear when I get to read the FSF material a bit later today.
