Thanks.
Corbett Wilson was told about the ferry flight on 8.10.1914, and the ‘delivery note’ (signed by Trenchard) was dated 10.10.1914.
He wrote to his mother on 16.10.1914 that he was hoping to get on that day, with the implication that he had arrived near Folkestone (he followed the railway from Redhill) the day before. On 19.10.1914 he wrote “Arrived here (St Omer ?) with the machine today.”
