Re: what to do on the plane?
quote Chocolate Soldier:Interesting writeup about the Payne incident from the owner of the charter company, apparently the pilot was a retired USAF Major who had been an instructor in low oxygen scenarios:Thanks, I hadn’t seen that before.
And I’m sure everyone that flies for the US military spends some time in a hypobaric chamber during training. I did once in a chamber, and once for real. The chamber was when my brother in law was in his navy primary flight school. We were visiting and got to go in it. We started doing something stupid simple like playing patty cake. As the pressure dropped, it got harder and harder to do it. You could tell something wasn’t right, but couldn’t do much about it.
And one time was for real – I was flying in the right seat of a friend’s King Air. We were taking the owner of the company to New Orleans, and they let 3 of us come along. On the way back, the two guys in the back were drunk and loud and getting a little annoying. So my friend flying motioned for me to put on my O2 cannula. We were at about 25,000 feet, and he gradually dumped the cabin pressure to about 15,000 feet. The guys in the back fell asleep in about 30 seconds. Before he repressurized it, he had me take mine off to see why O2 is required for all occupants above 14,000 feet. As I started getting sleepy myself, he raised it back to 8,000 ft and we had a peaceful ride home. The two meatheads in the back slept the rest of the way back to Dallas.
But if it was a rapid decompression, it would be the same effect as a tight rear naked choke – you’d have literally seconds before unconsciousness. And the temperature above 24,000 feet and above is ALWAYS below zero, so unconsciousness would be death in a very short time.
Re: what to do on the plane?
quote Chocolate Soldier:Another myth is the deranged passenger / BG opening the door at cruising altitude – impossible due to door design & difference in air pressure..Losing cabin pressure is not a necessarily huge problem in itself (more what’s caused it is the issue) – the remedy is to descend to a lower altitude.
Correct. Most of the doors open to the inside. And even if they didn’t, if they hinged to the outside, the hinges are on the leading edge, so opening them pushes against the slipstream. I’ve had a door on a Piper Arrow come unlatched in flight. It could yaw the plane like a rudder, but was impossible to open enough to even try to slam it closed. So it stayed that way until we landed. No way you could even budge it on a jet going 500 mph.
As long as the pilots are still conscious, it’s not too big of a deal. But it didn’t work out so good for Payne Stewart’s plane. A decompression that quick at altitude leaves a few seconds of consciousness, then the sub-zero temps would hit quick. Dropping below 10,000 feet quickly becomes very important.
Re: what to do on the plane?
quote paul:our airplane a LearJet 45 can maintain cabin pressure with a pax window being blown out. a bullet hole will not depressurize an aircraft as there are larger leaks in the typical airframe.Mythbusters did an episode on that. The worked their way up from handguns to shotguns, and none of them caused anything more that a hole and a loud noise. Next was blowing a window completely out. It sucked their dummy’s arm out, but the plane stayed together.
Finally they used explosives. Yep, that did the trick. It blew the top half away down to the flight deck, and pulled rows of seats from further up the plane towards the hole.
And for a real world example – there was a commercial flight back in July, a Boeing 737-300, that developed a 1′ x 2′ hole in the top of the fuselage right before the rudder. It lost cabin pressure, likely pretty quickly. But it landed safely. Really loud, really scary, but not deadly.
Re: what to do on the plane?
Seriously, it’s okay to be ever vigilant, but try to relax. At any given moment there are between 5,000 and 10,000 airplanes under ATC control in US airspace. I just looked, and right now, there are nearly 6,000 aircraft flying in US airspace. There are nearly 40,000 flights per day. So since Christmas, there may have been 400,000 flights in US airspace, and there was a problem on 2 of them.
It doesn’t hurt to be aware of what’s going on around you, but the odds of something happening are nearly zero. Just relax, and enjoy your flight. I don’t fly on commercial flights more than 2 or 3 times a year, but I’ve never seen anything remotely concerning even since 9/11.
Re: Sick all the time…need to keep myself up when missing classes..
I get a cold/night time cough every stinking fall, right when it starts to cool off. I took my yellow belt test all jacked up on sudafed just so I could breathe. I know how you feel. Claritin-D works well for me for long-lasting relief. The steam room helps some as well.
But until you feel well enough, just do anything you can. If you feel well enough to walk, go for fast walks.
But rest and recovery is critical. You can be training as hard as you possibly can, and eating right, but if you don’t get enough recovery time you’re just spinning your wheels. I’m prone to rotator cuff impingement, and it started bothering me again back in September. I kept going to Krav and pushed through it until thanksgiving, but then quit lifting for about 3 weeks, and went light the 4th week. Last week was my first full week again, my shoulder feel back to 100% again, and I can’t wait to get back in there tomorrow.
Re: what to do on the plane?
If you see anyone trying to light themselves on fire, that’s a strong indicator something is amiss.
Re: Fairtex v. CSI Shin Guards
I looked at the Fairtex ones, but went with Top King Professional. We practiced kick defenses the other night, and they were great.
Re: Are we being true to the system?
All we know from that video is that they intended to do a segment on a “new fitness craze” or something similar. Most people don’t put much thought into self defense, but lots of people want to “get fit”, whatever that means to them. Most of them now seem to be clogging my gym. Ahh yes, the “New Year’s Resolutioners”. At least they’ll all be gone in a month so I won’t have to wait while some skinny kid does 10 sets of bicep curls in the squat rack. But I digress…
Even if KM were getting “watered down”, TV segments like that would not be the way to judge it. You can’t judge the system, good or bad, based on a first lesson by a tv reporter, and with no information about the school, the instructors, or the students, you can’t even make a judgement on that particular school.
Re: christmas terror attack attempt
Here’s one that happened, AirTran wouldn’t allow them to fly on ANY AirTran flight, and they were just a normal family, and had been cleared by DHS or the FBI. AirTran still refused to let them fly on one of their company aircraft.
http://www.cnn.com/2009/US/01/01/family.grounded/
I did find more on the 6 imams that were kicked off the flight. The lawsuit was not because they were kicked off the flight, but was because they were handcuffed and detained. They reached an out-of-court settlement in the lawsuit.
I bet the reason they sued for being illegally detained is that they didn’t have any legal standing to sue over the removal itself.
Re: christmas terror attack attempt
quote JamesH:Yes AviatorDave the pilot has that authority, but in a world where our Seals are charged with assault because a frickin full blown terrorist mastermind got a fat lip, and where our cops have to consider every possible lawsuit before, during, and after they defend themselves, and our soldiers cannot conduct war but are instead asked to be cops….Do you think a Pilot would really risk an ACLU and CAIR lawsuit as well as possibly being fired from his airline for racial intollerence after pressure from those organizations? The Airline itself would be sued as well, then settle out of court for a few million $, which would immediately fund the next attack on the very same Airline.
This, I’m afraid, is the world we now live in…and it’s tremendously insane.I hear ya, but it happens quite regularly. It’s not company policy that allows them to do that, it’s FAA regulations. And the pilot’s union will back them up. The union would go crazy if a pilot was ever fired for an action he believed could affect the safety of his flight. The most recent example was a woman with a crying baby. It seemed a little excessive in that case, but she had to get off that flight and get another later one. I don’t think lawsuits against these actions go anywhere, as it’s a condition for buying a ticket.
I’ll look and see if I can find any lawsuits around passengers being denied from a fligt.
Re: christmas terror attack attempt
quote BradM:Paul,
“did anyone here read the story about the Airtran flight with muslims acting up.
”
Was that the one where about 12 muslims, scattered through out the airplane were talking load and aggressive on their cell phones to each other and one was on his computer. All refused to put them away when the flight attendents told them too. It was an on – off again situation with them being removed from the flight then allowed back on after being searched. After being directed to continue the flight, the air crew refused to fly and left the airplane. When a new crew was on board the majority of the passengers refused to fly and left the airplane, causing the flight to be cancelled.I’d heard about the flight, but not the rest of the story about flight crews and passengers. If that’s really how it happened, then I’m surprised the captain didn’t make them all leave. All it takes is for a flight attendant to tell the captain that one of the passengers isn’t cooperating, and they’re gone. The pilot is has legal authority to boot anyone off he so chooses if he feels it can impact the safety of the flight. The one I’m thinking of, I thought they were already enroute.
As for this clown, if I didn’t have a laptop or ball-point pen in my hands I could embed in his skull, I always noticed that knees seem just about face height for people in their seats. There are still plenty of things on a plane that could be used as a weapon.
Those of you that have done drills on the airplane mockup, what was and was not effective in those exercises due to the confined spaces?
Re: home defense weapons
For the UK, I used to suggest a jawbreaker in a sock, but apparently those are now illegal as well.
Here’s a little saying I’m fond of:
A handgun keeps someone off your person, a shotgun keeps them out of your house, and a rifle keeps them off your property.
I’ve got several of each, I’d probably grab the shotgun for things that go bump in the night – higher probability of hits when awoken from sleep, less penetration through walls, but can still cause lots of damage.
It kind of depends on where I am, where the intruder is, and where the rest of my family is at the time.
The less experience someone has with handguns, the more I’d lean towards a shotgun.
Re: AR-15’s
quote markx3:Thanks, that’s good info….At 50 yards I was shooting 2″ groups. For me that’s pretty good considering it was the first time I tried to shoot in over 10 years with a new rifle and a newly sighted in scope. At 100 yards it was a lot worse…so I need to sight it in better.
Maybe my eyes aren’t the best because at 100 yeards I could see the center target fine, but not the targets on each corner. That’s why I was thinking I needed a more powerful scope.
Thoughts?
How were you shooting? Offhand (freestanding) or resting it on a bench? And which ammo? Ammo can make a big difference. With good ammo, resting on a bench, and a new rifle, you should be getting groups 1/4th that size at 50 yards. Most new rifles with good ammo should be down in the 1″-2″ range at 100 yards area. Some are always 1″ or under, if the shooter does his part. Shooting from a rest will take a lot of your errors out so you can see what the rifle itself is capable of.
But you can put as much scope on it as you want to spend. If you’re going to be shooting at mostly 100 yard ranges, something in a 3-9x variable may help. Just don’t get a cheap one just so you can save money on a high-power scope. There is a huge difference in the lenses, the better scopes are far clearer. In other words, scopes are one of those things where you get what you pay for.
Re: AR-15’s
4x should be plenty for 100 yards. 4x should be fine out to about 400 yards or a little more. As a reference point – many scopes for military use are 10x, considered good out to 1000 yards.
Think of it like this – a 100 yard target at 4x is like shooting at a 25 yard target through the iron sights. Don’t think you need it so magnified that you can see every bullet hole. That’s what spotting scopes are for.
You want to use the lowest power scope that still lets you center the crosshairs on the target, it will give you the widest field of view and let in the most light.
I have a Leupold 3.5-14×50 scope on my .308, but at the 100 yard range near me it sits on about 4x all the time.
Re: Basic Strikes not fast enough the Krav way?
quote leejam99:its late and my eyes are heavy so i didn’t read through every post.. but here my take. every one is really focused on pivoting of the FOOT. but why? its not the pivoting of the foot that give you power on the punch, its your hips turning that’s making your foot pivot. If you just pivot your foot but do not engage your hips, there’s no transfer of power to you limbs. The only reason why your foot should be pivoting is because the rotation of the hip is causing the foot to pivot. it is your hips that give you the power, not the foot. if you don’t use your hips, if you don’t get your hip involved in a punch, kick, jumping, etc.. you have that much less power.That’s exactly what I was taught in boxing, and also exactly how they teach us in Krav. Pivoting the foot for a jab is just a tool to teach beginners how to get the hips rotating. Once that is understood, you don’t pivot the front foot on a jab anymore, but like every punch and even kick, you always rotate the hips.
