I stand corrected prospector, it was based around the crew's inability to achieve VHF contact. Still my point remains the same. As fourholes says though there have been numerous threads and years to rehash this particular debate.
Congrats to NZALPA for putting together an interesting and informative site. Reading both the Mahon and Chippendale reports fully will provide me with ample excuse to further put off my remaining ATPL study
