DT-III aboard USS America

Video on VIMEO: https://vimeo.com/193148172 LOWest Quality Video attached below.... same same Utube now. LOOK! how close the chaps are during the VL! with deck moving during the first STO and when chained later.

Many thanks 'bring_it_on' for the PDF which clears up the 'night vision goggle' testing SNAFU text on previous page which was actually NIGHT VISION CAMERA testing for the HMDS III which is an ENTIRELY DIFFERENT concept. FFsake! SLDinfo.

Nice video!

0:44 Interesting: do the outer pylons point more upwards?

Camera Lens play tricks & I have no idea about question. There are a few head on shots with minimal distortion of the various variations with pylons - you would have to look at them OR have a precise plan view drawing with pylons shown.

You can look for photos yourself and it should be obvious how perspective is distorted by cameras. Under an F-35C 'in close/at the ramp' shows some distortion front to back & sideways. A plan view drawing of situation is best bet I reckon.

THIS F-35C Album has a bunch of weapon / pylon / perspective photos:

Thank you for your reply and the pictures spazsinbad, it is pretty hard to see from the bottom.

I took a screenshot from that video:

Maybe it is indeed a lens trick, though if not it might have something to do with air streams when the weapon are released and/or in-flight aerodynamics?

'botsing' perhaps you do not understand what I wrote. Lens distortion is real. In the screenshot you provide above you see that perspective distortion. The under shots of the F-35C are MUCH LESS distorted but comparatively slightly distorted; because, for one, they are not truly underneath as a PLAN (with no lens/perspective distortion) drawing would show. There is also slight distortion from front to back. Perspective distortion cannot be helped - unless special cameras are used while the aircraft is suspended directly above the special camera lens.

The weapon pylons are fixed as shown. I believe they align with something but cannot prove it just by a photo. Try proving your case. There are plenty of those front on 'distorted' photos - usually with an array of weapons, some carried on pylons.

Various lens have different names for good reason - their properties vary quite a lot - with often dramatic effect on the subject matter. Look at the 'under' original photos before they were ZOOMed as seen above for better 'perspective'.

Have lost the URL for moment of the UNDER F-35C photos however the compilation below shows the two originals and how the perspective is distorted. I zoomed in and rotated slightly both photos but did not otherwise correct distortion.

They're not pointed out, they're pointed in :

(Actually, I think they're pretty close to parallel with the centerline.)

Good illustration of opposite effect from rear/under perspective (lens unknown). Yes how exactly are the pylons aligned - only the SHADOW knows - aligned with fuselage (what part?) or aligned with airflow? The beat goes on.

Aren't the pylons straight on, parallel to the centerline body of the aircraft?

Isn't there lens distortion on the photographer's camera?

Most lenses introduce some sort of distortion, but when it comes to the final image it depends to some degree on the processing done. Programs like Lightroom and Capture One include automatic corrections for lenses to compensate for these distortions. One way to tell would be to check the EXIF data and if that's been stripped out, you'd have to actually reach out to the photographer, assuming he did the final processing.

The question wasn't about toe-in vs toe-out, it was toe-up vs toe-down in the vertical axis.

....and where are the AIM-9 rails?

The question wasn't about toe-in vs toe-out, it was toe-up vs toe-down in the vertical axis.

This indeed, I could already not place why there were picture shown from the bottom where this would be the least visible.

I have drawn some lines to see where the angles meet. If there was an uniform lens distortion they would all meet in the same place on the horizon, which they don't. So either it is a non uniform distortion or there is a toe-up/down (caster) difference in the vertical axis between the pylons.

The Sidewinders on the outer pylons always seemed toed noticeably downward to me.
