Can you explain to me what "set back down here" means? I've looked up in dictionary and have found that "set back" is meaning "delay", but I'm not completely sure it matches my text. Also I couldn't find in dictionary meaning of "down here". Does that mean "somewhere where you are situated far away of me"? The text is:
Dad tried his transmission again, and Mrs. Coleman came on.
"This is Bime radio, go ahead."
"Roger, Bime. We just took off from there, and I've got a low fuel reading."
"Did you fuel at Sentani?" she said.
"Then you should be good to Yawsikor. You think it's an instrument problem?"
"Roger. You want to be safe and set back down here?"
