Smithsonian kinda, sorta admits to a lie

Jim, I'm too lazy to actually do the research, but I strongly question the
90 hp at/near the same weight as the Wright's engine... My recomember is
that Langly's engine, while a true engineering marvel for the time, was a
radial engine developing a bit under 60 horsepower at ~240 pounds ~4
pounds per horsepower... this was astounding for 1903

From the latest Sport Aviation: "Charles M. Manly designed the five-cylinder
water-cooled radial in December 1901 for the abysmal Langley Aerodrome, and
this technological marvel deserved a fate better than being installed in that
worthless contraption. This advanced engine weighed 124 pounds and produced
52 hp at 950 rpm." They don't say if there was a cooling system or whether the
weight figure includes cooling water or not.

By comparison, the Wright engine put out 12 hp and weighed 180 pounds dry. With
no cooling system, it could run for only a few minutes before the water in the
jackets boiled dry.

Great discoveries are not announced with "Eureka!". What's usually said is
"Hummmmm... That's interesting...."
