Let me get this straight, okay? Lois - who has absolutely no experience with a parachute - is going to drop into a wheat field (which is not flat and is therefore likely to at least twist her ankle on landing), gather samples of Kryptonite-laced wheat in a heavy lead-lined box which has every likelihood of being lost from the shock of opening her chute, and then get picked up on a tether from the same plane flying by? And you expect that no one will see and investigate a parachute floating down into a wheat field with several miles worth of visibility in any direction? And the pilot - who definitely should know better - agrees to this nutty plan?
Um, sorry, but this is almost as unbelievable as a flying man from another planet. The US Army has experimented with flyby pickup systems in the past, and the one constant is that the person being picked up is subjected to several tons of pressure on being yanked skyward. At the very least, Lois's shoulders and/or elbows would be dislocated, and since she's a 'plus' sized girl, that makes it even more dicey. I can't believe this will come close to working.
But then, maybe that's what you're going for, Lois jumping into the water without checking the depth or clarity or presence of monsters. It would be a terrific way to introduce tension and conflict into your story.
