How this record was checked
CSA successful-swim entry 2245 gives England, solo, one way, France to England, 1933 and 15:41. Dover Museum item d13102 transcribes the dated departure and arrival and names pilot Louis Courthes. The Between Wars exhibit supplies Isabelle but prints 15:45; certificate item d60116 prints 25–26 August in one caption and 28 August elsewhere. The selected dates follow the phase-specific affidavit transcription, while elapsed time follows the CSA entry. The conflicting accounts remain visible.
