Code Needs finishing Off Help Needed

[snippsat]

You can try this,i did look at download all .zip for all planes.
I let it run about 5-minute had no errors.
So if this is one time operation it may not be worth looking into concurrent.futures as i did show before.
Take break for a couple of hours ,and see if you have gotten all zip files.
