i dont know if it was a c17 it was just big and had 4 jets. i am kinda dumb to airplanes my good friend works on c17’s in s.carolina and my other buddy worked on c130s down in florida. thats about the only 2 planes that i know so if its a jet i consider it a c17 if its propped i call it a c130 thats about my knowledge on military cargo planes. i know what a b2 looks like also because my whole family on my dads side built them out at northrup (spl? ) in cali
