If the pilots died would you be able to land a jet liner at 40 000 ft?

It is an if/if, I flew enough in flight simulators to guide a plane somewhere, depending on the fuel and type of aircraft. Huge 747 nah, but small planes sure. I might fuck up the landing gear, and be confused as to where the wheel brakes are.

So I blew up my cottered cranks on a track bike I just recently acquired while accelerating... didn't crash, thankfully. No damage to the frame. Managed to roll safely to a stop. Need to replace the cranks. I want to use something modern and stiff because I actually intend to do some track racing on an indoor velodrome with this bike. I'm poor af but I train hard, so I'm using a steel frame. The bottom bracket is french threaded, so both sides are right hand threaded, one has a lockring, and they're 25.4 TPI.

I've found a company that makes a 103mm square taper bb that fits any 68mm shell (english, french and swiss). It uses a design that threads into itself and just sort of stays there with friction and some locktite, I think. I don't have any experience with more modern bottom bracket standards. Is there some way I could find a similar design that uses the GXP standard so I can throw a SRAM Omnium on there? Or any other non-square taper design?

>fucking French engineers, when will they learn?
How the hell did that thing even last as long as it did? If you've got quads at all you'd for sure shatter than fucking thing. When it was in one piece did it flex like a son-of-a-bitch when you sprinted? Seriously WTF.

I had it for less than a week and I got it in exchange for 8 hours of labor at a local bike charity. They couldn't use it because it wasn't drilled for brakes and uses tubular tires and I did some pretty heavy lifting for them. When it broke I was cornering really hard and then went into a dead sprint. I was only riding it in the street to get used to fixed gear riding. I'm so completely used to my steel frame road bike that I needed to tool around with it for a week or two before learning to ride on the velodrome.

I almost barfed when I finally got into work, SUCH a close call. You were bombing down Bute St just south of Robson, doing absolutely nothing wrong. I was pointed north and turning left into the alley. I only saw you at the last moment and hit my brakes. You never would have had a chance. I'm a very defensive attentive driver but I just didn't see you, even though you were right in the middle of the road. The problem was that you were wearing head to toe grey and had a narrow bike looking from the front. It's a bit uphill there for me so you were a small blob of grey on a grey asphalt background. I had to look right at you to see you, which I only barely did in time. Very sorry. I don't even think you were aware I was about to turn there by mistake.

Advice: wear more visible colors. Be aware of when people might not see you. Go slower unless you can see someone see you and ride defensively. If I didn't see you there at the very last moment, you were a goner. And I'm a cyclist friendly road star with 20/20 vision who doesn't want even a scratch on his car. Now imagine the average driver. Just a matter of time.

Wouldn't titanium be the most ideal for strength to weight ratio? Steel is just cheap.
>>
>>1216788
yeah but it's apparently difficult to weld properly so you pay even more than the Ti tubes for welding expertise. If you buy cheap titanium, the welds come apart, it's kind of analogous to the carbon=good but cheap carbon=death trap situation. you have to pay like double for QC. No big manufacturers even do titanium anymore, I think you have to get custom so nobody bothers, they just go carbon.

No, carbon fiber has a better specific strength.

I forget where, but I found this map posted on reddit of possible expansion/changes to the current Northeast train system.

hey /n/,
not sure this is the right board to ask, but let me try anyway:

I'm doing a private pilot's course, and the learning materails provided by the school are kinda shitty. I've found a bunch of good videos on youtube, but I'm more of a book-learning kinda person, so I'm looking to download/read online books covering the whole private pilot course (IFR would be a great bonus too).

Any help appreciated.

tl;dr looking for books (not videos) covering private pilot course

This is only sorta on topic, but I'm a sim pilot with little prospect of doing the real thing any time soon (medical reasons), and I'd like to learn how to properly plan and fly IFR. Most of the learning resources I can find are meant for real pilots and are priced accordingly. Is there anything decent out there that will help me learn the basics for free or at least cheap?

Hey I've got a question.

I've got to take an emergency flight with my girlfriend this coming week and we have two guinea pigs. I'm looking at google flights and I don't know how to do to buy tickets with those two suckers with us. I also don't know if I need any medication for them or what not. My mind if mush right now and I just had to ask.

Damn, these things are actually legit. I thought they'd ride terribly but they're pretty good, and great for cycling to work since you can throw it under your desk.

And have it hardly fold and ride like shit?
>>
>>1215875
I'd thought of one of those for my time-building adventures, but the BikeFriday frames look like they're not nearly as compact as a Brompton when folded up.
>>
>>1216132
My lovely foldable cost me 200 euro, it's kinda nice, the ride quality is good enough, but it has several faults. The 7spd deraileur was pretty shit, it was a tourney one, but I think that wasn't the biggest problem, all started when the sytem to attach the deraileur into the frame was extremely bad so it ended bending into the wheel, there was some friction and some piece got fucked and now I have 4spd instead of 7 (exploding knees) because i don't want to spend 20 euro on a new shit deraileur which will be fucked again in no time. The bike folds well enough, but it's pretty big to carry it around, the wheels are 20'' so it's only viable folding it to store it on the car or something else, and it doesn't have some lock for secure the folded postion so it will open at every small movement, so moving it is pretty hard.

Overall is a good bike, but not really fancy and if you want quality stuff this bike doesn't have it.I'm fine with the bike because it's pretty cheap and ghetto so I won't miss it really much if someone stole it while it's locked outside.What I really dislike is the lenght of the seat tube, I'm a long legs guy and riding a bike 10cm below my average ideal saddle height can be painful, as far I know bromptons have the option of picking seatpost with really high lenghts for big guys while the average foldable BSO probably have seatpost for 170cm guys.

>>1215639
I haven't ride a dahn but I have seen it and they look pretty expensive for the specs/looks. Saw a 500-600 euro one and didn't look way better than my shitter, yes, better deraileur (but still low tier) and a bit better folding system. That's why when I look a brompton I don't see it extremely overpriced because the fold system looks to be the best, the frame is nice, components are good and the deraileur is a internal hub way better than the ones in foldable bikes at the 600-700 euro range
>>
>>1215330
electric scooters are for invalids and fatties (same thing)
>>
>>1216227
Yeah, Brompton is more designed for commuting on trains and stuff. They fold quickly and easily, and fit anywhere fast. The folding mechanism is their #1 focus, although the bikes themselves are also great.

The higher quality Bike Fridays mostly just focus on fitting inside a suitcase so you can put them on an airplane for less than $600. They focus on road and touring bikes that you can take with you to other countries, even if it takes an hour to fully unfold.
They also make crappier cheap ones for commuting, which is probably what everyone here is badmouthing them for.

I've heard it said before that Brompton makes FOLDING bikes, while Bike Friday makes folding BIKES.
