First, seniors don't really bother everyone. It is mainly only freshman who are bothered and all three upper classes have a role to play in their training. As a freshman you will have to adapt to the college classes, to athletics at a mile above sea level, to wearing a uniform and keeping it and your room inspection ready, to various customs and courtesies, and you'll be expected to memorize aircraft from the Air Force inventory as well as quotes and historical information. It is designed to be very overwhelming. Sometimes you'll combine multiple of the aspects and be doing pushups while reciting a quote while in blues before a meal.
The homework kind of depends on the class just like any school. Some classes are "fuzzy" and focus more on writing papers while some are "techy" and focus more on mathematical problems. A techy class might have problems that you must do before each class while a fuzzy class might have a paper due each week. It all depends. However, assignments will never just pop up making you choose which one you must do. You will be given a syllabus at the start of each class and you will know exactly what assignments are due at what points in the semester. Then it is up to you to look at all your classes and decide when you are going to accomplish each. Maybe sometimes you'll have to work for a good deal over the weekend if a bunch of stuff is due the following week, but there is always plenty of warning when things are coming due. The only time you'll really need to decide between accomplishing assignments is if you mess up and don't realize when something is due.
You can fly planes but you can also graduate without ever touching the controls of one. We do not take classes on how to read aeronautical charts or navigation, those are the sorts of things you learn in pilot training. There is the soaring program where you go to the airfield and fly gliders as either a summer program or during the school year during your PE double block. Another similar program is the jump program where you freefall parachute out of a perfectly good airplane 5 times. By far it was the most rewarding program I did at the Academy. There is also a flying team; however, it really isnt a place where you learn to fly. You must apply for it and those selected usually already have a good number of hours.
If you want to know what intercollegiate sports we have you can look that up at goairforcefalcons.com, but if you are asking about intramurals then the selection is pretty vast. As sport seasons change so do the available intramurals. Just some that I can think of off the top of my head: Cross-country running, bicycling, tennis, soccer, flickerball (sport pretty much only known to the military and prisons), tennis, basketball, softball, ultimate frisbee, and others that I can't remember immediately.
The food is ok, but nothing to brag about. There are a few meals that I miss, but very few.
Since many of the teachers are superior officers you would treat them as such, but the academic atmosphere is very relaxed. If you so say sir/ma'am every so often then you are pretty much covered. You don't have to be scared of them or anything. They are VERY helpful. They all have time outside of class for you to come by and get extra help (we called it EI - extra instruction) if you are not understanding the class. You can even bring the homework and they will walk you through step by step and basically do your homework with you until you understand. For the fuzzy classes you can also often turn in a paper early and they go through it and point out corrections before you turn it in for an actual grade. The teachers are really there to help you actually learn the information, but it is up to you if you want to take advantage of that or struggle through.
