It's a possibility. The whole point of the IS is counteract the shake caused by movements in your hands/body. If you're steady enough or have the camera mounted on a tripod with the IS on, it could introduce errors into your image which may be the blur you're describing. I've learned this the hard way, doing night captures with the IS accidentally on, and the errors are magnified with longer exposures.
I don't have any experience with the 55-250 IS lens, but a quick search revealed that the 100-400 weighs over 3 times as much. I have pretty steady hands as well; however, the longer the focal length used, the more effective the IS becomes. In low lighting conditions, it's a godsend! Canon claims up to a 3-stop advantage with it on; your miles may vary. During the daytime, I'll usually switch it off. It does soften up the image very slightly with it on, but I'll let your eyes be the judge. You should be able to "see" your IS work, as well as even hear it.

The IS is rarely on nowadays. It seems to me it causes some camera-shake looking blur when it is on, because my hand is steady enough, even when I'm shooting slow.

What about turning off the IS on a long lens like your 100-400? As steady as I am, I haven't ever experimented with anything longer than 250mm (55-250 IS). I didn't really use the IS when zoomed out all the way even while shooting birds. Thanks for your advice!

You won't regret it.
Correct.
As mentioned already, it'll all really come down to just mastering the technique(s) and plenty of practice. Just as a side note, I usually disable the IS with anything over 1/500th of a second. The sensor isn't exposed long enough at that point and the mechanics of the IS become relatively insignificant.

I'm saving up for Canon's 100-400mm L.

I believe that lens has two modes of IS.

Like Ram said, if it is jets, go FAST! I will be the first to admit that i do not have a steady hand at all. For me when i go out to El Centro to shot the Blues, i crank it up to 1/1250 or even 1/1600. Just all depends on if you have enough light, but just bump your ISO up a bit. Most people will probably disagree with me on shooting that fast and that you should get your F-Stop more in the sweet spot, but for me, I really care about sharper pictures more.
I also had another friend give me a couple of other tips. One make sure to shoot threw the subject. Just remember to keep panning with the aircraft when you shoot. Another one, which is more of a trick, is the do a double shot. What i mean is that sometimes people have a tendency to squeeze they trigger hard which can shake the camera. So if you click down and hold the trigger so that it will take 2 or more shots you avoid the jerk of pressing the trigger for the subsequent shots.

Jets are a luxury, photowise. You can crank up the shutter speed as fast as you want, which makes things easier.
yes, your thoughts are correct... its all practice. I've been practicing for at least 4 years and I still am not satisfied with my panning skills - but they are much better. If airplanes are in short supply, practice at the local highway. Stay back about as far as you think the airplanes pass by, error on the side of closer though. Start with a fast shutter speed, maybe 1/1000. incrementally drop the shutter speed as slow as you can go and get shap-ish photos.
IMO prop planes are more difficult because they demand slow shutter speeds. jets, just crank it as fast as your f/stop and ISO will allow.
perfect practice makes perfect
