1. Jump Run Direction

Oops, the 10 second note was a typo. The math was right though, 9 segments of 20 seconds each equals 180 seconds. (I've fixed that in the other post.) As for the 1/2 mile for a two way, you may be right. Here is what I said... My post was long enough the way it was. I just used a half mile example throughout for consistency sake. There are a lot of variables as mentioned, and as you suggest, that should be added into the equation to determine the appropriate distance of separation between groups. Size of the formations, type of formations (big way rw, small way rw, freefly, tandem, aff, crw, wing suit, etc.). That would be quite an administrative task to try to get each type of skydiver to know the subtleties of exit delay calculations to the extent of knowing... IF you are a two way and following another 4 way or smaller (which is NOT a skysurfer or wing suit flyer) THEN take a 10 second delay BUT if you are following an rw group of 5 to 12 then take a 15 second delay or 12 or larger then take a 20 second delay, blah, blah, blah, , blah, blah. (Again, don't use these number, its for discussion. Make your own decision.) It seems that it might be more simple for the operator to post a note someplace like the loading tent or near the door of the aircraft that for today the delay is X. Remember one of the things I said was that you need to determine what distance you want and then the math will help with determining the amount of delay. If you don't know what distance you want for separation and you don't know the ground speed, you will never be able to know how many seconds to delay between groups. Who knows how would be the best way to implement a safe delay between groups. Continue researching and teaching I guess. (Thanks for finding the typo/mistake.) -mh.

3. Jump masters responsibility

I have no knowledge of the pilot Mr. Hill or any knowledge of the Cushing dz. My comments are general observations about the industry and have no reflection of any specific dz or operation. This is not true. Every dz pilot must at some time fly their very first load with actual skydivers on it. Flying skydivers is different than other types of flying and dz pilots should receive appropriate training before flying jumpers. It is unusual for any pilot outside of skydiving to gain experience flying under the conditions that jump pilots fly in. Very heavy weight at take off. Slow flight speeds at heavy weight. Moving cargo / shifting center of gravity. And then suddenly very light weight for decent and landing. Also, during all of the varying flight characteristics, the pilot communicates with the jumpmaster in the plane, the enroute or approach radar controllers, the local CTAF, all at the same time as monitoring the flight and operation of the aircraft. This is not true. There are many dz's that will not pay their pilots enough to hire very experienced pilots because the very experienced pilots will not work for the rate (sometimes nothing/free) offered by the dz. This is true. But, a person can get a commercial pilots rating with only 200 hours of total time. Of that, at least 40 hours and usually more was logged as a student pilot. This is not true. As mentioned before, spin recovery is not required training for a private or commercial pilots rating. Also, in a situation of severe aft center of gravity, this can make it very difficult to recover from a spin even with extreme competence and appropriate pilot reactions. Also, jump pilots fly in an environment of heavy weight and low speeds. This alone is a recipe for trouble. While it should be taught, it is not drilled into many student pilots enough about the relationship between weight of the aircraft, density altitude (temperature) and stall speed. If the weight of the aircraft is close to or over the aircraft maximum gross takeoff weight, the stall speed will be higher. Add to this situation where you have a student on the strut and suddenly he drops off and then the JM moves toward the rear of the plane in order to make room for the student sitting with his back to the pilot to slide over to the student exit position, and suddenly the plane is placed into a very rearward center of gravity situation. This also will increase the stall speed. It takes an experienced and trained pilot to manage all of these variables and most new jump pilots do not receive sufficient training for these flight conditions. Just some thoughts and observations. This is not an attack on gerrgoin. He simply provided an opening that allowed for adding some of my opionions to an important topic.
4. What do skydivers in Iowa do during the off season...

Answer: Climb Ice. Don Briggs who jumps at Paradise skydives in Vinton, Iowa has put together one of the best ice climbing facilities in the midwest. A competition was hosted last Saturday sponsored by Red Bull. It was a lot of fun. The tallest of the four silo's is 75 feet tall. Here are a couple of over 200 pictures that I took there this last Saturday. Between Doc John and I, we also took four and a half hours of video that we're going to compile into a documentary of the event. (Still waiting for summer though), -mike.
5. Which Speedlite Flash to use ?

Some time ago, Quade posted a link to a site with a lot of information on flash. http://photonotes.org/articles/eos-flash/ I have the 420EX and it won't rapid fire multiple frames without taking too much of a delay to re-charge. This is an excerpt from the site... "Flash units with rapid-fire capabilities: Speedlites 160E, 300EZ, 420EZ, 430EZ, 540EZ, 550EX, 480EG. Flash units with no rapid-fire capabilities: Speedlites 200E, 220EX, 380EX, 420EX, ML-3, MR-14EX, MT-24EX, 300TL. " I am buying the 550EX (maybe two of them) before the spring season starts. I have an unused 420EX for sale. -mh.
6. Good article about Model Releases

Found this to be an informative article. http://www.danheller.com/model-release.html#2.1 Hope the clicky link works. -mh.
7. Pilots check-in

I logged the time in all of the different aircraft and the crossings while working for an aircraft sales company. The Pacific crossings were done once in a Piper PA-31-350 Chieftain to South Korea and twice in a Cessna C-303 Crusader from Japan back to the states. This is off of the top of my head but the Atlantic crossings were done in Piper Malibu's (3), Piper Seneca II & III, PA31-310 and 350's, Cessna 303, 310, 335, 340, 414, Beech Barron, Duke. There may have been something else but I think that is it for the crossings. At the time, the trips were such an adventure you don't think you'll ever forget any detail. However, if I could do anything over again, I would document the trips better with a journal and more pictures. It was a great two year adventure. -mh. edited to add: I agree with your comment about ditching under canopy. I regularly carried my rig with me.
8. Pilots check-in

Commercial, Multi, Instrument. Never got an instructors rating. Just over 1,000 hours multi and just over 1,000 hours single engine time. Almost all piston, less than 50 hours of turbine time. Time logged in over 65 different models of airplanes. (This is kind of a stretch or opinion as C-182, C-182RG, and Turbo C-182RG were counted as three different models.) Almost all different models of Cessna, Piper, and Beech piston singles and twins. Flown 26 Atlantic crossings and 3 Pacific crossings. Still log about 100 flying hours a year but haven't done an ocean crossing since '95. Current Skydiving ratings: AFF-I, Tandem-I, D12622 Former Skydiving ratings: S/L-I, IAD-I, Pro, S&TA
9. External Flash

Okay, when can we see the pictures of this new rig? You've described exactly what I'm planning to do. I don't have the 550's yet but I'll get them ordered soon. Did you need to do anything special, or need any special equipment to get the two flashes to communicate wirelessly?
10. A Terabyte In A Cigar Box

Yeah, every server that we put together here at work, we build as scsi raid 5. I like it a lot and as poor a job as I do at home backing up (like never), I really like the idea of having that reduncancy.
11. A Terabyte In A Cigar Box

I saw that Sam's club had a 200gb internal drive for \$150. http://www.samsclub.com/eclub/main_shopping.jsp?n=0&oidPath=0%3a-23542%3a-33761%3a-33794%3a-33796%3a725404&coe=0&BV_SessionID=_SC_1974990145.1074209706_CS_&BV_EngineID=cccladckfljgfjgcfkfcfkjdgoodflg.0
12. A Terabyte In A Cigar Box

This is what I spec'd out today. I'm considering buying this to upgrade my home computer. Does anyone have any experience with something like this? If it works the way I understand it, it would provide 500gb (half terabyte) of Raid 5 disk space for only \$856.00. Raid 5 provides redundancy so that if one of the drives fails, no data is lost and the drive can be replaced and the raid system will re-stripe the new drive and restore the redundancy.

13. whoops, how do i convert CRW to anything else

I've been using BreezeBrowser for RAW conversion. This software, developed by Chris Breeze, was created using the Canon SDK (software developers kit). http://www.breezesys.com/ The software also has a lot of other nice features for cataloging and previewing photos, creating web pages, sending pics as email attachments and more. You can download and try it and then buy it later if you like it. later, -mh.
14. Please send prayers and vibes for my sister

Jenifer, We said some prayers for you tonight from Iowa. Wishing you a speedy recovery. -mike.
15. Wow. I'm on the History Channel.

Congrats!!! Wish we had cable/history channel so we could see it. We're too far out in the country and we don't watch enough tv to justify the cost of a dish.
16. Diamond .3 users....

Deuce, I'll bet that you are right. I just haven't tried it before. I'll try it as soon as I get a chance. It might not be until the spring though. Jump season has pretty much come to an end here in Iowa. There is a small, small chance that I might get a day or two in Eloy at Christmas time but that is very tentative at the moment. Even if I do make it, I'm not sure if I'll haul my camera gear with me. Later. -mike.
17. Skydive Video Editors...

As far as I can tell from the add, it is a full version. I bought a different Pinnacle product, (the Pinnacle DV200), a couple of years ago for just over \$200 and it included a full version of Premiere 6.0. I don't use any of the dv200 tools anymore but the dv200 firewire card works with the Microsoft firewire drivers and Premiere can use that card just fine.
18. Skydive Video Editors...

The best way to get a cheap copy of premiere is to buy it bundled with some other manufacturer's firewire card. A quick search found this card from Pinnacle bundled with Premiere 6.5 for \$200. I've bought regularly from B&H and never had any trouble there. Edited to add clicky link. http://www.bhphotovideo.com/bnh5/controller/home?O=&A=ShowProduct&Q=&sku=296427
19. Diamond .3 users....

I typically have not used the 'sports' setting. How does this make for better slow-motion shots? My guess is that it would be analogous to a higher shutter speed which would requiring a larger aperture resulting in a smaller depth of field. Do you know how this setting will affect depth of field? (I'm just beginning to grasp these concepts with still photos and not sure how they apply to video.) I sometimes set my video camera focus on 'infinity' to avoid the changing of the focus to a non-subject object during a skydive. With 'infinity' focus set on my video camera, I've had good luck keeping the primary subject in focus even at a very close distance. This has worked well for me. Does anyone else do this?
20. Bath -- Once a year whether I need it or not.

Wow. Amazing examples of before and after. You said that you now have all of the supplies for cleaning the sensor. Could you give a little more detailed information on what supplies you have / used for cleaning? Thanks. -mh.
21. Today is my 1st skydiving birthday!!!

I had my 20th 'birthday' this fall. Sept 9th, 1983 was my first time.
22. Digital Rebel Problems?

A search on www.dpreview.com in the 300D forum finds a lot of error 99 complaints. Most but not all, point toward Sigma lens problems. http://search.dpreview.com/forums/search.asp?query=error+99&forum=1031 Good luck and let us known what solves the problem for you.
23. Digital Rebel Problems?

When the 10D came out, there were a lot of new camera owners that were getting errors that could only be re-set by taking out the battery. From what I read at the time, most of these errors were caused by older Sigma lenses that were not compatible with the new Canon camera. I had this problem as well and I ended up buying a new Canon lens for my 10D.
