Would have been interesting to hear the CVR from United and PAL!
Interesting? Sure.
Useful to the investigation? Nope.
They were straight for PAL and only missed them by 3 feet of less
I seriously doubt that. The NTSB never said that. That's been inferred by posters on here. Without having seen the raw data, radio altimeters report the closest obstacle in the signal path, including an aircraft fuselage. But they were low, granted.
