"But all's fly with the tents"

Posted by Miri Barak on April 02, 2004

The chopper is leaving the camp site with the sick skipper and his wife inside, and the narrator says:

"*But all's fly with the tents*, and John and Sandy settle in for their unexpected flight back to Auckland".

I have a feeling that "all's fly with the tents" has some idiom hidden in it, but which one?

Thank you very much
