Just adding another perspective (figuratively and literally). When I learned to fly gliders many years ago, the two hardest things were takeoff and landing. No surprise there. Steering a plane around in the air isn’t hard. Obviously, in a glider there is no going around after a botched approach so planning the pattern is critical. That said, if you enter the pattern at the correct altitude at the correct place and at the correct speed, you will have pretty wide margins. The spoilers provide great glide path control and you can muff up the timing on the turn to base pretty seriously and still land at the intended spot. Speed control is critical. To fast and you can bounce or slam the landing. Too slow and the glider can stall and drop. Also, glider can go a long way in ground effect if no effort in made to flare or employ spoilers. When you touch down on one wheel, your butt is inches from the ground so your speed (35-mid 50s depending on the glider type) can feel much faster.
The takeoff part involves formation flying, a skill some pilots never train. You aren’t just being pulled along by the tug 200’ in front of you. You must actively fly to remain in the proper position. No easy feat in such dis-similar aircraft. Early in my training my instructors would remark “Boy, that tow pilot just can’t stay in front of us” as I over-corrected again and again. It took a while but one day it just clicked, much to my instructor’s and my surprise. It still takes some concentration , especially in turbulent conditions.
Anyway, if there is a glider operation near you, see if you can get a ride. We love taking power guys up for their first glider flight to see what its all about. Not to mention non-pilots who have no idea that you can actually go up after releasing from the tug.
