Really, why all the fuss about John Marsh? I think you guys are missing something big time.
If the FAA has set up a system that receives letters/reports such as the one from John Marsh without the report having to be a) from a professional involved, or b) from an eyewitness, then John Marsh is just making use of the system as the FAA designed it to be used and should bear no criticism. If you don't like that system then you should be expressing your views to the FAA on the setup of the system
If on the other hand, the FAA has certain rules about who it will accept input from, then John Marsh's input should be bounced if it breaks those rules - NFA
Just as LTD was encouraged by some of you to use the correct system in filing a report, so John Marsh should be allowed to use the correct system, if it exists.
