“very probably before 1950”
H. G. Wells
Writer and social forecaster · United Kingdom
The world at the time.
Wells extrapolated from active experiments by Langley, Lilienthal, Pilcher, Maxim and Chanute. His book expected powered flight rather than declaring it impossible before 1950.
What happened.
The Wright brothers achieved controlled powered flights on 17 December 1903. The occurrence was well inside Wells’s stated upper bound.
Predicted vs actual.
| Metric | Predicted | Actual | Variance / caveat |
|---|---|---|---|
| Successful powered flight | Probably before 1950 | 1903 | 47 years before upper bound; not a point estimate |
The counter-signal.
The Wrights’ 1901 glider suffered lift and control problems, leading Wilbur to despair temporarily. Those engineering failures were a real obstacle, although private American experiments cannot be assumed to have been known to Wells.
Verdict.
Reasoning: sound · Outcome: right
The familiar claim that Wells said flight was impossible until 1950 reverses his wording. This narrow forecast is right, while his separate forecasts about aviation’s transport role and aerial tactics require separate judgments.
Cause of death / explanatory lens.
No cause of death assigned
The lesson.
Are we evaluating the original deadline or a later paraphrase?
