Please do not destroy, scrap a single remaining Fokker F28-4000 jet even in 8 decades, they could be converted into a military variant in the future by being modified by having eyebrow windows removed, changing their right side door to one like the Fokker 100 has. Removing or bringing closer the last pair of windows to the second last pair. Military variants can be modified from passenger variants that were flown in the past. Planes that are more than 88 years old like the Dc-8 still exist. There are still other very old models that can be in service.
