Sentry SOPs involved strapping in, gloves on, securing all loose items etc (although often still working down back although some kit switched off so books and sortie paperwork often still on desk tops). Once stable behind tanker, Captain's discretion to allow "minimum" movement through the aircraft to achieve tasks (not for cooking). Often allowed passengers (one at a time, escorted by a crew member) to have a look at tanker through doorway for a few seconds - again, once stable behind the tanker.
Mind you, whenever we had an SOP then the AEOps would break it because they knew better...... Watch how quickly they unstrap after landing despite the FRCs! (and they knew better because "thats what we did on Nimrods").
