But today I tried to get fuel from a KC-135 and after 30 seconds, i disconnected due to loss of control. Then i tried 10 mins to re-connect and eventhough I got the boom into the fuel door, nothing happened, operator didin't move the boom. Then I made a quick search here and found this topic, then closed and re-opened the door and voila, operator connected again.
Edit: Lol ok I read the manual, never mind, i have to press the nws ok
