[@MegaOscarPwn] A few Allied pilots who were downed over France, tried fleeing to Spain and from there traveled to Britain, for example. Simply moving to US without reporting to the British military could be labeled as desertion, so either, for example, make Oscar go to Britain via Spain, report to the authorities and get assigned to the TSF via the cooperation of the SOE and OSS. Or, Oscar says "Screw it!", flees to Casablanca, gets a visa and travels to the US, gets caught by the authorities and is taken back into service and assigned to the TSF.
