The RAF does have mobile Isolator Units (basically airborne isolation sets) which have been used in the past to bring VSI and possibly highly infectious patients back to UK. The kit had even passed a USAF decompression test.
At least it did, together with a highly trained team - at Lyneham. Wonder where it is now!
Now with TMW at Brize, called the Infection Control and Prevention Team. Last used to move a patient with Corona virus from Edinburgh to London last year.
