[4] The post-First World War air force was consolidated in 1920, (180 flying squadrons had been reduced to 25 on active service) and medical provision for the RAF would be undertaken at existing army hospitals apart from a few key RAF locations, such as at Halton which had the apprenticeships school.

[10] At the start of the Second World War, Halton was used as an initial assessment point for aeromedical evacuations from the continent (Europe).

[15] The admissions and treatment records for 1945 showed that the hospital at Halton admitted 11,311 patients, and all but eight of these were Royal Air Force personnel.

[18] The remains of the hospital were demolished in 2008, and a housing estate has been erected on the site,[19] which covered some 20 hectares (49 acres).
