I think you will find that there is.
A few years ago the increase in brain cancers in the US (and presumably 
other countries) was said to be of epidemic proportions but as far as I 
am aware that predates the use of mobile phones.

The biggest controversy surrounding the Wright brothers is whether they 
were actually the first to fly. I gather New Zealand has a prior claim 
with Richard Pearse.

But claims of 'first' are always dubious. We all stand on the shoulders 
of our predecessors. Interestingly, nobody seemed to doubt him. Not so 
much of the snake oil suspicion in NZ I guess - a particularly sad form 
of Pathological Scepticism.

Item 23 in this newsletter, Pathological Skepticism by Bill Beaty, 
is incorrect about the nature and the chronology of the controversy 
between the Smithsonian and the Wright brothers. Langley himself had 
nothing to do with it. As far as I know, he accepted the Wright's 
claims. He died in 1906, long before the controversy erupted, and two 
years before the mainstream believed the Wright's claims.

The controversy was caused by Langley's successors, especially 
Walcott, by Glen Curtiss (a commercial rival who used Langley's work 
to try to break the patent), and by A. G. Bell. Bell awarded the first 
Langley Medal to the Wrights in 1910, but in his speech he belittled 
their accomplishments, making it seem as if they were merely students 
of Langley. Bell was a great man but this was an ugly incident.

In my opinion, Langley did not contribute much to the progress of 
aviation.
