“To be or not to be, that is the question” what does all this mean?
Whether ’tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing, end them. To die, to sleep;
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That flesh is heir to — ’tis a consummation
Devoutly to be wish’d. To die, to sleep;
To sleep, perchance to dream. Ay, there’s the rub,
For in that sleep of death what dreams may come,
When we have shuffled off this mortal coil,
Must give us pause. There’s the respect
That makes calamity of so long life,
For who would bear the whips and scorns of time,
Th’oppressor’s wrong, the proud man’s contumely,
The pangs of despised love, the law’s delay,
The insolence of office, and the spurns
That patient merit of th’unworthy takes,
When he himself might his quietus make
With a bare bodkin? who would fardels bear,
To grunt and sweat under a weary life,
But that the dread of something after death,
The undiscovered country from whose bourn
No traveller returns, puzzles the will,
And makes us rather bear those ills we have
Than fly to others that we know not of?
Thus conscience does make cowards of us all,
And thus the native hue of resolution
Is sicklied o’er with the pale cast of thought,
And enterprises of great pitch[1] and moment
With this regard their currents turn awry,
And lose the name of action”

would a jet work under water?
It would use large hydrogine fuel cell, or some other way of seperating the H2O, for under water (it would use the hydrogine for fuel and send the oxygin to the pilot) it would use jets similer to the ones on jet skis but larger.
It would use scram or ram jet engines for flying threw the air due to the fact salt water destroy a jet engine with moving parts.
the shape would be like a f-14 tomcat when the wings are folded back
http://www.allwoodwings.com/1-MilitaryPlanes/IMAGES-MilitaryPlanes/F-14,SwingWing,VFA-142,swept.jpg
I know it prob won’t work but I just want some ones opinon.
the AIR will go to the pilot to breath and the hydrogen will be burned or what ever
the fuel cell is for under water only
key words UNDER WATER water has 1 hydrogen an 2 oxygen atoms so there for water= air to breath and hydrogen to use as the fuel
batterys would run the fuel cell and as I said, it mite not be a fuel cell it could be somthing else if somthing better comes around.
my grandfather worked for Mcdonald Douglas aircraft before the merged with boeing and he has connections in boeing who I have submited my idea to.
I got a letter saying that the tech is here now but the only thing that would keep it on paper is the shape and size
this isn’t a collage paper i’m writing some i could care less about my grammer right now
I’m addressing many things here:
let me get one thing f-u-c-ken straight I know the diff. between a jet ski and jet.
It would have 2 jet ski or pump jet engines and 2 scram jets (scram not ram, I know the diff.) scram jet engines have close to no moving parts so they are lighter then turbines.
next, you can kiss my white *** about my grammer. Having 5-6 words misspelled words is not the end of he world. I don’t care when it’s on yahoo answers cause I’m not trying to impress you with grammer. I can type circles around you if I needed to. I’m a straight A student in my keyboarding class and when I’m at home I can type however I f-ing want. THIS is not the long run
one thing I WAS wrong about and can admit it is the 1 hydrogen and 2 oxygen, I was speed typing and mixed them up my B. its 2 hydrogen and 1 oxyen.
it would use normal fuel for the scram jet engine. It would ONLY use the fuel cell for under water seeing thet their would be plenty of water.
ranting continued:
scram jets are not a type of turbine
http://en.wikipedia.org/wiki/Scramjet
the pump jet is not a turbine either if that was what you talking about.

here’s a pic for all you jackbutts(not all of you are) i know that it ***** but it’s scratch work
C:\Users\lassi\Pictures\sea snake.jpg
it has the horizotal elevators near the nose just like the Dassault Rafale
http://en.wikipedia.org/wiki/Rafale#Variants
taking out the need for them to be at the tail
(for better stablity under water)
sorry about the link can’t it on here

Motion Sickness and Deep Sea Fishing?
Anyway should I take drugs to prevent it just in case then…or just find out if I do get motion sickness or not? I’ve been on long road trips via car/rv/busses no problem. I have no issues with air travel bumpy or smooth either. If you do suggest I take drugs..what kind do you recommend? are they easy to find like in Walgreens or other pharmacys? Thank you
