Isn't this similar to the situation where the pilot lines up on final and finds that their approach is going to put them exactly into the near hedge?
Answer - reduce drag - get rid of whatever drag flap you have.
If this was discovered late on then the aircraft will be at the min-approach speed which is below best glide for most aircraft. Thus get back to best glide speed.
Finally, far batter to pancake under control than cut your head off with the wires so - dive at a point just short of the hedge (cables) convert speed to height and promptly lower the nose as the hedge(cables) are cleared.
To see how you will get on, try the exercise at height - dive to best glide +say 15Kt and pull up at a predetermined height until the airspeed reads Vs+5 before lowering the nose positively again.
Note height gained and the time taken from pull-up to push over (so that you can work out distance travelled).
Now for the important bit, after the nose is again lowered, establish level flight at just below the height you pulled up at and see how long you can maintain level flight before the stall and check the attitude - is it the touchdown attitude?.
Best to talk about these things and practice at a safe height than have to make it up when it does happen.
