@Waspie Thanks very much, by 'backseat' do you mean aircrewman or observer?
Yeah maybe
@Pontius or
@Magic_Mushroom might have some info.
All 3 services have exchange programmes for a variety of branches (ie not just aircrew).
For the RAF, we have fast jet exchanges with the USAF (F-15E, F-16 Aggressors, F-22, B-2 with F-35A likely to be added soon), USN (FA-18E/F and EA-18G), USMC (FA-18C/D and AV-8B), RAAF (FA-18A moving to F-35A shortly and FA-18F), RCAF (CF-18A) and French (Rafale). Multi-engine wise, we have guys on stuff as varied as USAF C-17 and MC-130 to RAAF E-7 and USN, RAAF, RCAF and RNZAF MPA. We have RPAS guys with the USAF and helicopter exchanges on Army AH-64, RN pingers, USAF HH-60s and US Army MH-47s, to name but a few. We also send student test pilots to the USAF, USN and French schools.
As
@Waspie and others say, candidates apply (overseas tours are all voluntary) and are selected based on a number of criteria but will generally be experienced. There are actually not that many applicants for each one as the same demographics will also be in the running for things like Qualified Weapon Instructor courses and the Reds. Perhaps more importantly, there are quite serious financial and domestic implications (eg schooling, spouses having to give up work etc) to an exchange tour which put many off. These days, if you go on exchange to the US, you’ll probably return after 3 years at least £5K out of pocket not including loss of spouse earnings.
We’ve also reintroduced sending a small number of student pilots through the USAF flying training system, largely due to the MFTS debacle. They used to return at the Tac weapons stage but I’m not sure what the plan is now; they also have to learn what clouds are!
To the best of my knowledge, the RN have a variety of FJ exchanges but most are currently one-way to build up FJ experience. These are USN and USMC centric on FA-18C/D/E/F and AV-8B. Once our F-35Bs are properly in service, I’d expect these to reduce to historic norms with perhaps one each on USN F-35C and FA-18E/F, and maybe a USMC F-35B slot.
