Very sorry for your mom Ady, I hope she'll recover quickly.

Don't feel like you have to reply the posts here, I think everyone here understand you have more important matter to attend to. We'll wait for you as long as you need…

Meanwhile I have posted an analysis on my tread that should enlighten the ATAT-Snowspeeder discrepancy in ESB. It's huge so Here's a quote:

…

Below the most obvious scale establishing shot of the At At is portraying a length of about 30 m length (height varying between 24 - 26 m, depending of the stance):

…

The crushing scene however shows an AT-AT foot that would make a 18.5 m AT-AT, not very convincing and inconsistent with all the above said. I'd say it has to be fixed (as said on Ady's tread). (the red lines are the 30m ATAT & the green ones the 18.5m ATAT):

I've made a mockup with a foot scaled up to 140% (to make a 30m length AT-AT).
The original shot:

My mockup:

And here's my conclusion chart:

Give me your thoughts.
