SHJ - at least one had a medical fit, operated by the Armed Forces Medical Service - conversion pre-dating the B747-100 flying hospital. The VC-130Hs were convertedaround 1977 when Saudi Arabia was only starting its rapid economic rise. I think only 2 still remain in service with 1 Sqn RSaAF plus 3 L100-30s Alsalam Aerospace Industries "has also upgraded three VIP Hercules since 2008 – one civilian L-100 and two RSAF C-130s – with new cockpits and elegant new interiors, that include bedrooms and suites, as well as state-of-the-art entertainment and communications systems." The Al Saud is a large family
I remember as a youth in the 1970s seeing Saudi C-130s as regular visitors to Ringway/Manchester, I have a vague recollection of seeing a non-camo one.
I was interested to see a Shadow R.1 orbiting over Pompey and then slightly further north yesterday afternoon.
