I believe you're thinking of the Me321 glider.
The Me323 was the powered version of Me321.
Thanks for the correction, the numbers get gloppy with me on occasion. I'm certainly talking about the glider and not the six-engined -323.
The point, that having three a/c take off easily while strapped together is difficult, and that the Germans took measures to get around this, is still germane.
