Hi Don..
A pleasure to have another ex-RN chap aboard
The original texture is DXT3 which you can't view unless you use something like DXTBmp.. a lovely little freeware texture convertor. So.. I opened up the file in DXTBmp, converted it to 24-bit colour, opened it up in Photoshop, saved it as a psd file, duplicated the original texture as a new layer, deselected the old layer then reduced the opacity of the duplicate. Then, this file was saved as a .bmp file in 24-bit. I then opened the original file in DXTBmp and sent the alpha channel to Photoshop where it was saved as it was (trans.bmp). Finally, the new Glazing.bmp file was opened in DXTBmp.. the newly saved alpha channel (trans.bmp) called in and the lot saved as Glazing.bmp in DXT3 format ;-) Well.. you DID ask
Glass is a bit of an unknown quantity to me.. especially how it reacts in the dreaded FSX so no one was more surprised than me when it appeared to work

The important thing is you're up and running
The original texture looks like it's been taken off a scrap lying on a workshop floor and the scratches were far to wide and pronounced. No way would any aircraft outside a junk yard have glass like that.. let alone a fighter bomber where the whole concept is to be able to see something and either shoot it down or bomb the cr@p out of it
