Out of focus, happend to me quite a few times and that mad me really mad. It could have been a really nice shot but I screwed it up.
When it comes to technique we are on the same wave length Gary, mostly I focus on the nose and go along, nevertheless sometimes the autofocus gets irritated as it cannot find a target. For all shots onboard through the windows I disable the autofocus as I had better experience with it.
If I remember well there is a webiste from Nikon or Canon just dedicated to Aviation photography with tips and tricks. I don't know the URL though.
Maybe someone else knows.

I think we have all had this problem more than once... One of the many challenges of shooting fast-moving, metallic objects, is the ever-annoying light reflection that confuses the heck out of your AF. However, I have only had this problem in continuous AF mode, single servo mode seems to work a little better, but its much trickier to work with.
I agree with your panning technique, I just make sure I never focus on the highly-reflective parts... nose-cone, windows, and tail-cone.
To most people, the sky is the limit. To those who love aviation, the sky is home

The more I hear about autofocus, the more I'm glad I've stuck with manual focus! Focus on the nose is generally you best bet, particularly with approaching aircraft a) the cockpit tends to draw the eye, get this blurry and the pic is in trouble, even if other parts are sharp. b) depth of field extends further behind the point of focus than in front.
In profile shots, again go for the cockpit. This MAY mean engine pods, wing tips out of focus, but this is better than the other way round.
When focusing, I tend to pick up the aircraft some way out and start tracking the cockpit - I get a rough focus fairly quickly and sort of hunt around that point as the plane gets closer - easier to do than describe!

I dont know if I have a problem or not, I wear contact lenses, which means that even with the lenses in my sight is not 'spot on'. Therefore if I use manual focus, am I adjusting the focus to suit my eye and therefore throwing the actual focus out slightly? I don't know if my problem is with my eyes or my camera lens. I've even sought advice in this forum before about changing my Sigma lens for a Nikon lens.
Anyhow with the autofocus switched on I've missed loads of potentially good photo-opportunities as the A/F decides to refocus at the exact point that I want to depress the shutter release.
C'est la vie!!!

It's really frustating when I want to shot and the camera don't wants to shot, this happens sometimes when I want to photograph planes moving fast on the runway, mostly with those white liveries. Sometimes I focus on some point of the runway and after passing to manual focus, I wait till the plane passes over that point of the runway, not 100% perfect. Sometimes I'm following the plane but predicting that the camera will not be able to focus, so I pass to manual while composing the picture wich is a kind of stressing.
English is not my natural language, I don't understand what do you mean with "...focusing on the nose first then pan along the aircraft..." what is pan along the aircraft?

I don't know which cameras you use but I have not experienced this kind of problem with autofocus - not at all.
I use the following cameras: Canon EOS50E and EOS300. Both have more than one focusing point and that way at least one of the points is usually on the plane and the camera is able to focus correctly and quickly without lens "hunting" for a point to focus.
As a matter of fact I have never regretted selling my MF gear and moving to AF-age, AF focuses always 100% correct and that way you don't have to worry about focusing when taking the pic.
If I were using a MF camera or a single focus point AF-camera (with line-type, not cross type focusing sensor) I would _always_ focus to some part of the plane where are vertical lines, ie: tail, engines, wing, nose, etc...

I've got some other kind of focussing problem. I do my Pictures with a NIKON Collpix 990 and the manual focus isn't realy useful for moving objects, so I have to use autofocus. So when the temperatures are realyy high the camera seems to be unable to focus on the plane. I mean whe the air is really blurry because of the hot concrete its very hard to get sharp pictures. Frustrating but I think I have to live with this disadvantage of this digicam because I like the advantages.

I hate that too! I have missed countless shots to the AF. The problem is, the lens on my camera very easily gets knocked out of focus on MF mode. I will most likely be getting a 70-210 lens and keeping my old Pentax(I love that camera - I hate the lens it has now).
Has anyone got the Quantaray 70-210 f4-f5.6 MF lens? I'll be choosing from either that or the Sigma 70-210 f4-f5.6 MF lens. But i'd like to see a result from the Quantaray lens.

Mate, I either point at the nose gear or main gear to get the focus and then centre the aircraft and take the shot. Also if the aircraft has very clear title on the fuselage you can just point at that.
Quite a simple trick really, but the proof is in the pudding!!!
Anyway, I am off to get the dingo outta the dunny as he's drinking all my VB!!!

Just a tad! I don't think you've quite got the panning concept yet ...
In order for an image to be sharp, it must have no perceptible movement in relation to the camera at the point when the film is exposed. By using a fast shutter (eg. 500th) the film is exposed for such a brief time, that the subject has not moved a significant distance during the exposure time (unless we're talking VERY fast jets). But when you use a slow shutter speed, say 1/60th, an aircraft will have moved a noticable distance in that time, causing a blur on the film. To counteract this, you can "track" or pan the aircraft with the camera, so that there is no movement of the subject IN RELATION TO THE CAMERA (though now the background will begin to apprea to move, and reproduce blurred).
If you pan in the opposite direction of movement, you will INCREASE the relative motion (camera moving one way/aircraft the other) and get a very blurry subject.
