F/O Blogs.....your right mate!!! FDR,s and Cockpit voice recorders are no doubt an accident investigator,s tools of the trade(if the A/C is so equiped),...many A/C do not have these Devices....I have flown 727,s,on contract(South America) where the operater has removed said devices....as they were not required.....(dont ask me why,I was in it for the $$$$$$$$$$)
To think this jorno,s objective was to film for accident investigation is a little way out there for sure......but the recording was made and it use(s) will probably be garnished as evidence....
You may or may not be aware,but the FAA and others have been pushing for years to get video recorders in the cockpit,in addition to the FDR and cockpit voice recorder....and it has been debated before on this forum.....
any and all evidence will be critical for those responsible in handling this tradgedy...........PB
