Got talking to a nice old chap today in my local bookshop (great bargains on Spitfire stuff, but that's another story)- he had his British 1st Airborne Division veteran's badges on... one thing he came out with was that he always wanted to know why the tow rope on his glider always appeared slack when airborne, not taut as he thought it would have been. He's been wondering about this for sixty years. I said I might know some people who could help....any ideas?

Could it be an effect of drag on the heavy rope?

Yeah, and the weight of the rope. Also, he's viewing it from an angle that really promotes an appreciation of any 'drop' in the rope. From a perpendicular view the 'drop' would be much less noticeable, although perceptible.

The rope is so strong and thick that it doesn't have to be taut to do its function and thus will hang a bit.

or

The weight of the rope causes the glider to close up on the tow plane as the rope tries to "fall down".

Cuz the glider had some liftforce and speed of its own?

It's the weight of the rope. See:
