sorry if digging up old thread. What is to stop one from saying they broke their foot playing a non high risk sport (basketball, soccer) vs from downsizing too quickly?? Obviously anything serious enough to require a trip to the ER asap is going to be harder to cover up. But injuries where you can come in a couple days later? Asking for a friend.

I dunno when it is too tight but you know it is at a safe tension when your packer starts complains about your pull up cord being too tight

Well if you just saw an aircraft below there is no way you can fall fast enough to get down to it to hit it. It's the plane you can't see that you are at risk of hitting! "Below" doesn't necessarily mean directly underneath you. If it's at a lower altitude, and moving towards you at 120 mph from a mile or two away, it could intersect with your freefall path. So you don't just check underneath you, you also need to scan around the horizon in a circle, as much as possible. What would you say is the reliability of your attention when you are in the door about to do a skydive to spot an aircraft 1-2 miles in horizontal distance? Particularly when you are not looking at the spot before the green light goes on, i.e. first group already left and pressure to set up in the door is on? I think the biggest risk for collision is at deployment altitude this is where the more amateur pilots are more likely to be flying around 3000-4000' and more prone to miss out on the fact that they are flying over a dropzone. Most pp's on their Cessna 172's won't be flying above 9000' routinely. Commercial operations should know enough to stay out of DZ airspace although as we all know from scary pictures and videos this is not always true! DISCLOSURE: IF YOU SEE A PLANE BELOW DON'T JUMP!! ...even though I still think the probably of hitting a plane you see is extremely low

the most important thing is to read all the fatalities and accidents related to cameras and review additional things that can go wrong, not having 200 jumps. That being said with 30 jumps no way you can jump a camera, it would just be information overload. Fresh off A license you are still nervously checking all your gear, don't know order in the plane etc... and unless you have a lot of tunnel you won't be able to get any footage anyways. Around 100 jumps (if you get to 100 fast and actively jumping) is when you start getting comfortable enough that you could add a camera IF you understand all the extra thing s that can go wrong (knowing snag risk is not enough, you need to think about snag on reserve bridle, snag on another jumper main bridle, snag on front riser, snag on D ring in the door or in free fall, etc...) it's really an issue of "you don't know what you don't know"

if it's so different how come tunnel instructors who never skydive before, then start skydiving and then are super good at free flying at

If you ws a valkyrie I'd recommend also getting a valkyrie reserve so you don't miss out on a swoop after all the cutaways you'll have

skydiving is boring. but the longer of a break you take between jumps the more better next one gonna be. Problem is after 500 jumps even if you take a few weeks off next jump is still boring

sounds like the FAA physical is a manufacturer requirement, not a law. I think you're a lot better off getting cleared by your family doctor who knows you a lot better than an aviation expert who never met you. It'll be harder to hide serious medical conditions from someone you been seeing a long time.

I could see it from a sit but he did it in an angle so I'm wondering if he got some kind of special mouth switch for zoom!!

anybody know how to use zoom from the camera during a jump? https://vimeo.com/172592312 The guy who made this vectorfest 2016 video said he used the zoom on the camera in this. Wondering how that would work in free fall? It looks like he would just randomly zoom in/out while free flying from the camera as opposed to zooming in from editing software

that's a nice setup thanks for sharing it! Just find someone who is into 3D printing and they could make a nice looking mold to place where the a5100 hangs out to eliminate the snag hazard.

Nice! I currently have 2 go pros for tandems and switching to GoPro + plus a5100 for tandem stills. And I want to shoot Freefly formations with ax53, the tonfly I got though doesn't hold both ax53 and a5100 at the same time unfortunately. I currently have a fuel so I could probably add the dual top mount which would probably hold a5100 and ax53 at the same time if need be. Do you find a ring sight is mandatory for flat top mounted stills/video? This is because there is quite a large difference in the angle of my GoPro I have between belly/tandem and Freefly so I have no idea how I will be getting a center shot with a top mount camera that does not tilt up or down to adjust angle!!! Gonna have to start using my neck!

what is a good first cam to get when you're looking to step up to something more pro than a gopro? I've been looking at the sony a5100 16-50mm. I'd like to be able to shoot between tandems and freefly formations I'd also like to be able to get shots of hop n pops with enough zoom that you can see the buildings and roads on the ground nicely. Is 50mm enough for that or does quality of detail on the ground more a factor of megapixel as opposed to zoom?

I googled the London marathon race results and the top 24 finishers male age 55-64 were all sub 3 hours finishers. If you don't know anything about running in marathons a sub3 is considered like the 'mecca' finish time for marathon runners. It is extremely difficult and is pretty much a Boston qualifier if done in any age group. By BPA logic nobody should be allowed to skydive unless they run a 2hour 50min marathon

on here cause I just found out UK has a 55 age limit ban on skydiving. What a joke. I thought they left the EU cause they didn't like stupid rules? #BPAsux

California, USA. At the same time, he says he will NOT have ANY parachute on him. So, did they get the FAA exemption to do that? Daily updates: https://www.facebook.com/Luke-Aikins-998360006849439/?fref=ts If he uses an airplane, then the FAA needs to be involved. I assume there is a process to get exemptions from FAA rules, like taking a special assumption of risks etc. If Red Bull does something like that, one thing I am assured : that all the caveats are covered, and all legal Ts are crossed and lawyers' Is are dotted. But still, it needs to be cleared with the FAA, parachute or not. I think the whole point of skydiving without a parachute is called "FREEDOM"... not "FAA regulations"

if you're jumping a tandem canopy the boots are fine since you don't have to slide out or run the landings

This just about covers it. I learned to jump at a DZ that had the current World Champions and more than a hand full of other icons of the sport. Never once was I refused a signature. As was mentioned before, pick a good time, introduce yourself and ask their name. I have never heard a jumper say he wished he/she had not taken the time to log so much. Sparky this is actually cool I never really thought of it this way. 10 years from now there's proably gonna be so many people that are gonna wish they asked me to sign their log books,

if it was a static line try a course that starts at altitude from an Otter. Likewise if you were scared of heights and did AFF1 at Otter dropzone try static line

every time you are not on the net you are in free fall by the laws of physics You need to learn physics Gravity is pulling you to earth in freefall. The way your body acts is different in the tunnel. You are using your body to try and stay off of the net in a tunnel. Basically holding yourself "up" of the net. You use your body differently in the sky, because you are not trying to hold yourself up. You use the air resistance in a similar way to change direction and relative speeds. But they are different, and don't directly and automatically transfer from one to the other. lol. "pushing yourself off the net" is slowing your fall rate, the same thing you do if you need to slow your fall rate in the sky. I'm assuming you don't do much tunnel because as you progress you can fly in higher wind speeds and then you don't struggle staying off the net gravity is pulling you to earth in tunnel it doesn't matter if it is artificial fan creating the air resistance or in the sky. There is an equal force of air resistance going opposite direction of gravity in both situations none of that matters because everyone with low jumps numbers and high tunnel time kills it in free fly which proves it works.

so is that a recent change on their website? I may be planning a trip to California soon if that's the case

Once I tried to get someone to sign my book back a couple of hundred jumps. (I logged all my jumps but never made the effort to ask people to sign off until after about a few hundred jumps). Think it may have been a tall order, he signed back about 20 jumps.

considering your jump numbers being 2725 I am assuming it has just now began to interfere with your jumping? Apart from stating the obvious (quit smoking!), you can buy a cheap O2 sat meter at a walgreens and compare you O2 at altitude to other jumpers, which can easily be placed back into any regular sized pocket in a standard jumpsuit before jumping. I think it's normal to go under 90% w/o COPD(?) But if you find you're down to under 80% or you are significant less oxygen saturated than other jumpers on the load (like >10% difference) then it's probably getting to be not safe.
