davelepka, DougH I was hoping to ask some simple questions regarding Skydiving and want people to stay on topic without making False Accusations, Speculation and Comments that are Off Topic especially if it involves me, which it has. I'm not here to be your friend or to be popular. I don't need to know and have no desire to know who you are. I'm interested in asking some questions and learning something. My questions are on topic and relative to the forum. Would you politely remove your off topic posts to my questions before I contact the website administrator and have them do it for you? If that is necessary, then you will be wasting their time and my time because of YOUR inappropriate public behavior. If I wish to remain anonymous, guess what, it's NONE OF YOUR BUSINESS and it's probably a good idea. Ever hear of Identity Theft, Psychopaths, Sociopaths, Cyber Bullies, Mentally Ill Violent people who want to harm you etc? Guess what, they exist everywhere. Your responses are Off Topic, Accusatory, Speculatory and you are saying this in a public forum. Amounts to inappropriate behavior. If you feel the need to Speculate, Investigate, whatever...Use Private Messaging, your telephone and leave your responses out of my posts. I do not want you to post your responses to my questions if they are going to be off topic, accusatory and speculative

I found this info: Here is a break down of your jump ticket based on a small DZ, flying a C-182 with Continental O-470 series, 300 hours/year (2400 heads/year, 8 heads/hour or 4 heads/load) and going to 10K MSL. ->Firewall forward OH reserve ( engine, prop, mags, carb, gov, engine mount, start, gen/alt, exaust, bafflings and etc): $25000 / 1500 hours / 8 = $0.26; ->Typical annual costs: $2500 / 2400 = $1.04; ->Aircraft Insurance and liability: $5500 / 2400 = $2.08; ->Fuel per load (avg) 7gl x $5.50 / 4 = $9.62; ->Pilot: $10 / 4 = $2.5; ->Extras parts, oil changes, unscheduled maintenance and top OH: $15 p/h / 8 = $1.8; ->100 hours inspection: 12 hours x $65 x 3 / 2400 = $0.97; ->C-182 airframe depreciation: $5 / 8 = $0.62 Direct total cost (not including office expences, ground crew, rent, facilities, utilities, taxes, free beer and etc...) : $19.00 Each DZ is different. There are more efficient, low cost and/or high volume operations out there. There are shortcuts too. here: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4096994;search_string=cost%20per%20airframe;#4096994

It's the flat pitch of the propellers that are acting like a giant fan to slow him down, yes? If you could not control the pitch of the propellers, would this type of descent be possible, or would you go to fast and risk ripping the wings off? Can a Cessna 182 make a descent like the King Air? What would happen if you put the propellers in reverse while in these steep dive? Could you stop the airplane or make it go back up if you could keep the tail over the nose? Does Mike Mullins take observers sitting up front on a regular basis or does he prefer to keep observers out and do they pay the same rate of $26? Does his jumps ever get cheaper than $26 or is that the going rate? I'm comparing this to the Twin Otter at the Parachute Center which costs only $15. Is his King Air the most high performance/fastest jump ship in business?

So I assume that Don Kirlins worked most of his life in the Drop Zone business, and does not have much profit for all the work he's done? He may have covered his expenses, but there was nothing put in the bank for retirement?

I never took Physics in High School or College and am trying to research these questions that I've asked. Not trying to make things difficult, just asking some simple questions that pop up as I'm thinking about other posts that are somewhat related. Sometimes, the question if pretty simple. But when you get on Wikipedia, it becomes more complicated to the point where it's confusing, then I return to the forum looking for a simple answer. Just found the anwer: "A typical skydiver in a spread-eagle position will reach terminal velocity after about 12 seconds, during which time they will have fallen around 450 m (approx 1,500 ft)" at the Wikipedia Free Fall site.

1. Supposed you jumped off of a building, bridge, cliff, balloon...how many feet would you have to fall before you reach 120mph? Answer: "A typical skydiver in a spread-eagle position will reach terminal velocity after about 12 seconds, during which time they will have fallen around 450 m (approx 1,500 ft)." Found here: http://en.wikipedia.org/wiki/Free_fall under Examples. 2. People who jump from heights into pools, what are their speeds as they hit the water and how high are they jumping from? Are they reaching speed of 120mph? Answer: Dana Kunze, Record High Dive holder at 172 feet, tumbling type feet first entry. http://www.youtube.com/watch?v=4uHkyMh9FW4 Still looking for his speed at entry.

I asked a few questions, so I'm not sure what the "Yes it is possible", is answering.

If you were to build a device, say the size of a 10x10 room, and toss it out of an airplane/balloon... and you wanted to remain inside the device not touching the floor and not touching the ceiling, what would be the vertical speed of your fall? And if you could do this, that would be 0G, yes?

Less than 1G is what you feel if you are in a car, and it quickly descends down a hill. You feel that the car is falling faster than your body and your body feels as though it is lifting out of the seat. At the point of you lifting completely out of your seat, but not thrown into the ceiling, you are at 0G's, correct? Anytime you feel less than 1G, you are at Negative G's, correct? And Negative G's begin at .999999....of 1G and less, correct? When does all this begin?

Does the airplane spiral down around the jumpers or does it descend at a plumb/vertical angle alongside the jumpers?

Not sure how to phrase this, but I'll try. Is it possible to roll the airplane, dive the airplane, and always remain at 1G and will the water in the glass always remain level, or will the glass remain on the dashboard and the level of water change angles in relationship to the glass? I guess there's level to the horizon and level to the relationship of the glass when it's level. So if you closed your eyes, would you know if the plane was rolling if the water remains level in the glass during a roll?
