Yes, the liberties taken with how things work in the control tower were plain outta sight. One reviewer referred to "control centers", but I've never seen one. I have been in airport control towers, though, but only because I was invited, and while there may be some tense moments, nobody lets on while they are working the planes. When you're up there, it can be hard enough to understand what's being said without hearing stress.
And the guy in the Cessna didn't know what a transponder is? Uh, no - he did not get his license from the FAA or any other accredited entity in some other country. Yeesh.
But, all things considered, I did enjoy myself and if you just want to have a fun time, go ahead and watch it. Just keep in mind that it's about as far from real as you can get. Oh, and if you have ever seen "Airplane", watch the hair on the newbie controller as the plot moves along.
My jaw only dropped a millimetre or so watching the shenanigans going in that tower until we got to the part where the pilot in the troubled airplane apparently was unaware that he could control the direction of the plane with thrust to the right engines and then the left. Really. And no one in the tower was aware either. Sigh.
I was taught to fly straight, without a stick, rudders only, and to change direction in a twin using alternate engine power. It's kinda' like learning to fly 101. Granted, the pilot did need instructions from the tower to maintain the right headings, but then he spots the blazing lights of the runway and is off to the left of center. Sorry, if you're an airline pilot, you have more tricks up your sleeve than McGyver.
