JD-EE Now, what kind of chewing gum will you use to affix the front edge of the string to the window? I suspect common transparent tape would not do to well, nor would common duct tape. Umpty degrees below zero is not compatible with most adhesives I know that won't become a permanent part of the window.
airbus once had solved the problem to fix a vertical stabilizar on a fuselage.....
tape will work very well, but also this: open the window, hold a lace out, close the window....... will fix it for a test
yes please
