Unfortunatly Bill Grasha passed away in mid September 2023 as I could read, recently.
He did many contents for EVP like countless of callsigns, airport names, aircraft and helicopter types and different variation options.
There were many callsigns which he did, which I had requested, for civil and military AI.
Like Spanish A400M (DUMBO)
Bahrain C-130s (AMIN)
QATAR C-17 (LHOB)
and many more he released after I had requested them.
Also many many civilian callsigns like
LONGSHIP for FlyNorse 787-9, which Michael had looked for in this forum.
He also did for Flyadeal the callsigns (PURPLE and then ADEAL).
Also callsigns for all the Ryanair subsidaries.
He was also a FS9 fan like us, and I had tried to invite him twice to this forum.
My respect to him and his work he did for the FS9 community.
Thank you, Bill.
