Dudeness, sadly we are headed for a ban and forbid reaction from the various regulators - certainly in regard to carrying passengers in old aircraft . I believe it already exists for commercial operations in Europe. The three most recent crashes (DC3 in the USA, Convair in South Africa and Junkers in Switzerland) can only accelerate the usual knee jerk response from regulators as they move to cover their public service backsides.
Down here in Oz and the Shaky Islands we are still lucky enough to occasionally see a DC 3 on a commercial flight carrying passengers to the vineyards, or doing scenic flights, evening dinner over the city lights etc. The safety record is OK because the few operators are sufficiently diligent in their maintenance and pilot training. It is doubtful that they actually make a profit from such operations, but they persist for the love of it and recover as much of their costs as they can by flogging tickets to the public.
Do the public know the potential risks? Of course not! No one will market a joy flight in a DC3 by stating that if it suffers an engine failure there is a chance it won’t be landing back at the departure airfield, or indeed may not actually land on any airfield but possibly on a convenient beach.
Therefore, I fear these grand old birds will be soon be legislated out of commercial operation by the imposition of modern performance standards, requirements for ADS B, flight recorders etc.which will make them unaffordable for all but the most wealthy private collectors.
