anyone here believe in u.f.o's?

Yup, I believe in them UFOs...

It was 1994, my brother was five years old...I was cutting the grass with the automatic pulling lawn mower with my roller blades (smart huh?) and hear a car screeching to a halt. I realize my brother wasn't anywhere in sight...I blade to the car and see my brother dazed but not seriously hurt, he got hit by the Caprice, but not hard on his bigwheel. Obviously, my parents are flipping out, but that's the intro to the story.

7ish that evening, when it was dusk...my brother watching TV in the other room, bandaged and bruised calls out "Chris! Chris! Come here!"...I reluctantly get out of the sofa to see what he wanted and he simply points out of the sliding door. Now, from this sliding door, you are looking towards the top of Winburn Baptist Church behind a giant and aged pecan tree...and out of amazment and absolute fear, a floating saucer with flickering lights.

I run back into the living room and get my Dad...I show him the saucer and he simply replies "I see those all the time...." and walks back to into the living room. I stood baffled, wondering what the heck was he was talking about, follow him into the living room ask him what he meant and he didn't answer...so I ran back into the room my brother was in only to see the saucer was gone.

To this day, I can mentally see the saucer and paint that day in my head like it was yesterday. No one ever believes my brother and I when we tell people...but we know what we saw that day.

Unfortunately, when he called about the "crazy star" I couldn't pin point what he wanted me to see over the phone...maybe I should've paid attention in astronomy.

NO shit that was a UFO because you couldn't identify it.. Hence, UNIDENTIFIED FLYING OBJECT!! Not the same thing as ALIEN SPACE CRAFT!!

UFO's exist, that's not a belief, its a fact! Alien Spacecrafts on the other hand is thought true by illogical, superstitious, and might I add retarded people..

YOU GUYS ARE FUCKING DUMBASSES!!

My colleague is a aeronautical engineer, perusing a master's at Tech.. He is laughing so hard at you ignorant inbreeds..

Ok, so they fly 20+ million light years to earth, stop by and leave.. How do they know where earth is if they are 20+ million light years away? Makes sense right? NO.. This isn't even a "needle in hay stack" its purely impossible.. Need I say more? I am afraid so, since you guys are dumb..

Spacecrafts can't just enter and exit our atmosphere like they please, it is a lot more complicated than that.. Here, a little detailed explanation why (hopefully, this isn't too complicated):

This only applies to our atmosphere, other planets' atmospheres have different compositions and properties.. That being said, HOW THE FUCK do aliens 20+ million light years away know our atmosphere's properties?

Entering the atmosphere:
On entry, a spacecraft needs to be at a specific angle (this applies to all, even Alien Spacecrafts, its physics). The angle is very important when coming in (called the entry corridor), if it isn't right, you either bounce off (lifting entry) or crash on earth (ballistic entry). The right one is called a (glide trajectory). These are at speeds of mach 9 or 10.



Leaving the atmosphere:
A spacecraft needs to reach ~13,000 mph to get to low earth orbit.. Then, it needs escape velocity which is reached at mach 34 or 25,200 mph (comparison speed at sea level).. You say a Spacecraft sits in our atmosphere and then just fly's away? That is impossible, the amount of force exerted from the Spacecraft needed to leave the atmosphere is astronomical.. You would see/hear/feel a hug blast which will probably take out half you town.. See the huge fuel tanks on Spacecrafts? Wait, you guys are probably going to tell me they have anti-gravitational Spacecrafts or something..

I don't know why I am wasting my time on this..
