"Swiss Air 111 was able to communicate until the very last minutes. Had they not delayed to dump fuel on a relatively standard approach procedure and instead made an immediate emergency descent and landing they may even have survived."
This is not correct. Read the report.
"Based on these factors, it is evident that even if the pilots had attempted a minimum-time emergency diversion starting at 0114:18, it would have been impossible for the pilots to continue maintaining control of the aircraft for the amount of time necessary to reach the airport and complete a safe landing."
