In order to illustrate how bad this movie is, let me tell you a story about my younger days.
If you read some of my other reviews here on IMDb, you'll see me mention that I flew F-4 Phantom fighters in the Air Force back in the late '70s to early '80s. If you read my review of the movie RED TAILS, you'll see my rant about how George Lucas was absolutely the worst person possible to have produced that movie, and how nobody in Hollywood has any clue about what a real dogfight looks like, and how Lucas is the worst offender, having bamboozled America's moviegoing public into believing that his depictions are an accurate depiction when they're the farthest thing for it.
Back when I was in college and Air Force ROTC, I was part of a small clique with my two best friends, Ray and BJ. Ray was in my class and BJ was a year behind us. All three of us were aspiring fighter pilots, and were allotted to attend flight school upon graduation and commissioning. Until BJ flunked out during Ray's and my senior year, his junior year. BJ decided to go in the Air Force as an enlisted man when Ray and I graduated and went to flight school. In the meantime, he decided to transfer his credits and enroll in a Community College and finish his Associate's Degree before enlisting. One of the courses he took was in Cinematography, with the final course requirement being a short subject film on Super 8mm film with no sound.
With BJ's family's home (and the Community College campus) being not far from our college campus, he recruited Ray and me to help him with his short subject. He decided to do a film depicting a dogfight between F-4 Phantoms and Russian-built MiG-21s. We used a large 1/32 scale model of a Phantom that I had, and smaller 1/72 scale models of another F-4 and two MiG-21s, one of which BJ built just to sacrifice by setting fire to it to depict it going down in flames. We built a Phantom cockpit mockup out of spray-painted corrugated cardboard boxes, and BJ doctored up his old high school football helmet and other athletic equipment into a flight helmet and oxygen mask (using duct tape to fasten the mask to the helmet instead of the metal "bayonet" clips that real mask/helmet combinations used. I caveat this by saying that while Ray and I had spent time at F-4 bases for ROTC summer training, neither of us would see or actually participate in real dogfight training for more than another year, after completing undergraduate flight training. At the time, we didn't know any better, and BJ storyboarded his short subject film based on the dogfights depicted in George Lucas's original 1977 STAR WARS movie and an old 1958 Korean War movie, THE HUNTERS with Robert Mitchum and Robert Wagner. (That film, we later learned from experience, which was made with USAF cooperation with real F-86 Sabres and with F-84F Thunderstreaks painted up as MiG-15s, still left a lot to be desired in depicting the intricacies of dogfighting and made Mitchum's character look like a one-trick pony!)
Cinematographically, BJ's old short-subject Super 8mm silent film was ten times better than GREYHOUND ATTACK. I'm absolutely serious and objective. That includes the helmets and oxygen masks and the cockpit mockups.
By the way, the average US Army Air Force pilot in World War II was 23, the average enlisted bomber gunner was 19, the average squadron commander was 24 to 26, and the average group commander was under 30. And they had height and weight standards to get into flight school. I don't think any of the actors playing aircrews was under 40 or would have met military height-weight standards even adjusted for age. And what was with the supposed British MI-6 intelligence analyst who couldn't make up his mind if he was a proper upper class Englishman or a good ole boy from Alabama?!?
The positive things I can say are that the writer/producer/director's heart was in the right place. And I congratulate him for having the chutzpah to actually release this turkey!
