Pointy end of raindrops Can't Post

Just wondering... when flat flying, jumping in rain hurts because you fall on the sharp end of raindrops; that's old proven knowledge. But what about in wingsuits? It should hurt less because you're hitting them side on. The drops are thinner from the side, and the point faces upwards.
Plus there is a burble from your helmet so you shouldn't be able to feel rain on your face much at all right?

If flying really efficiently for distance, what should hitting rain or ice feel like? Should there be any difference in sensation at all? We don't get much rain down here in Aus, but you guys in the other hemisphere might have done this a bit more...

Where's you get your old, proven knowledge from? The bonfire?

Google is your friend...

Rain drops are NOT shaped as you (and maybe most) think - with pointy bits up...

Probably wet, or cold.

It is a well published fact that they are - but thats a side topic - just to stop the argument before it begins - the original 'Pointy End of Raindrops' forum topic closed thi argument a few years ago - as per the quote below:

The little pointy ends can impale you and plug up your pores so you cant breathe thru your skin anymore.

Didn't Mythbusters do a show on that?? Laugh

Its the humidity in clouds that is has small enough H20 droplets that can in fact block the pores on our skin and stop the O2 osmosis from which we get most of our O2 from.

http://www.skydivejerseyshore.com/faq.htm#Whuffo

But how would pointy rain in the sky influence the perception of how efficient one's flight is when flying? The sensation of the direction that the stinging comes from would surely change as our ratio of altitude lost to distance travelled changes, so would this give us an ability to estimate how efficient we are flying? If so? What would the most efficient flight 'feel' like?

It would be different between different wingsuits right? As depending on balance an the body shape of the individual, each one would have a different 'most efficient' angle of attack. But assuming it is something that is similar for most suits, what would a real efficient flight feel like? (specifically in terms of rain)

I'd say cold. And probably wet.

You also must know to be careful flying in freezing rain conditions. The pointy ends of the raindrops become basically tiny upside down icicles, and since you're falling through them they can shred your suit not to mention cause profuse bleeding.

Worse, your flightpath overhead may be responsible for triggering the dreaded "random sky shredder" syndrome produced spontaneously by cold clouds which has been causing random fatalities among pedestrians and occasional housepets for centuries. When you fly through a freezing raincloud you disturb the airmass, tumbling the frozen drop shapes, which, once destabilized, tend to fall point-down, resulting in a uniquely hazardous form of diffuse sharp hail falling over anywhere you flew in which the conditions exist to produce it.

This is why we have cloud clearance rules that we never ever break. We do not want to be responsible for induction of inadvertently aggressive weather phenomena, its difficult to insure for, and whenever there is a "random sky shredder" fatality there is an investigation. If there were any wingsuits operating in the vicinity there are often some very hard questions and a great deal of FAA scrutiny for a long time to come.

Be safe- avoid freezing clouds.

Normally I would agree with Lurch but what if you have a suit that goes up? Combined with a double rainbow? Would you then be able to "skip" like a stone on water on these rain drops?

Ugh so many questions...

It feels like 'ouch'. Or rather, '***OUCH'. On any exposed skin you have.

Trust me, been there, done that Pirate

So don't jump through clouds for fear of causing an atmospheric disturbance?

Does the wind beneath clouds (outside n op regs breach) hit exposed skin at all if you're flying for speed? Backs of the hands I guess? But would it make a trickle of rain down the front of your suit, or stinging on the back of your neck etc?

Not really, but then when I plan on flying near rain I do so in full tactical body armor both to fend off the sharp raindrops and just in case the Homeland Security assholes open up on me with ground-based 7.62 turrets. They've been a bit antsy lately, having nearly shot down a glider recently because the guy didn't obey commands to land fast enough.
Its a rough sky out there... to be prepared, search the internet for the famous "Mall Ninja"... read and learn... The same tactical approach the Mall Ninja brings to bear against hostiles targetting Macy's works against aggressive weather phenomena. Give it a shot, you'll see...

Hahaha! That guy is classic! Just spent a while reading a lot of his adventures... They sound good, but are probably bull$hit. I can tell because he didn't provide one link to any footage on any of his stories. We all know that if you didn't have camera then it didn't happen. ;)

And we also know that cameras are a safety tool, they let you see what went wrong after your AAD fires early and causes a bear fatality ;) The apparent link between camera and rate of incidents is only because having camera means more of your friends can see that something cool happened. Not because they are responsible for causing an 'incident' :)

I expect that many of the newer jumpers are unaware of the Adventures of Nippleboy. Classic indeed.
