I’ve never had a problem with lowering the shield to get onto the moon
OK, so I was exaggerating when I said I always had a problem with it. The scene does work as is, but I still think that my other reasons stand. It does seem like a massive inconvenience to lower the whole shield. It would also create an feeling of isolation as once the strike team lands, they are totally cut off form any outside help. I’m not certain but I believe the coms did’t work through the shield either (in RO) and I don’t think that anyone from the strike team (in ROTJ) contacted the rebel fleet during the whole battle. With hindsight (If I’m right) that seems naive as it communication is key in battle especially if the plan as not worked. But this would make sense if they actually couldn’t communicate.
But hey that my last word on this subject.
