Relax PhotoFixer3. This old Airman has a special place in my heart for BUFF. I know He's Old and the B-1 has newer equipment, but Buff is over fifty years old and I worked on him in the seventies and he was around a long time before that. He's still here and that is outstanding. Please remember that as old as he is He's still here. Let the old Bird go on the Mission and he won't let you down. God Bless America and all her people in uniform protecting us. I'm glad you came back to me.
