I'm just posting this cause it was pretty cool. I live in San Antonio, it is not uncommon to see military aircraft daily here. Anyways, I was waiting for the bus when i saw a massive black helicopter. I didn't notice till it passed that it made no noise except for a few seconds after it had passed me. It was pretty cool. I live close to the medical center and hear helicopters all the time, they are only a fraction of the size of this massive one making almost no sound at all. I also have had the pleasure of seeing a green fireball at around 11pm while standing outside having a smoke. Just wanted to share my experience.

I live in Corpus Christi Texas and sometimes go on to CC Naval Air Station I have seen the large black helos there

they are called BLACKHAWKS..
Flat black w/ no markeings

YES, just to note I wasn't making this post to act if I had seen something way beyond the norm, It was just cool for me to see one, and none of my friends have the ability to acknowledge how cool it was. I just wanted to brag in front of people who would know what I'm talking about.

Ok you need to be aware of a couple of things here and provide more information.

i saw a massive black helicopter. I didn't notice till it passed that it made no noise except for a few seconds after it had passed me...., ....and hear helicopters all the time, they are only a fraction of the size of this massive one making almost no sound at all...

Answer to lack of sound, wind. Even if there is apparently no wind on the ground there may be a significant breeze even a few hundred feet up. This can often cause any rotor or engine noise to be blown away from the observer making it appear almost silent. Further you haven't really told us anything about the helicopter at all. What shape was it? Did it have a twin or single rotor? How far away was it? What approximate altitude was it? How did you gauge it was "massive"? Was it actually black or a dark shade or just appeared black in silhouette. Why does this seem out of the ordinary to you?

I also have had the pleasure of seeing a green fireball at around 11pm while standing outside...

Common and familiar but always spectacular. Almost certainly one of two things, either an asteroid rich in copper, or a defunct satellite re-entering the atmosphere.

The green fireball i went by fairly quick, and would not have been able to take a picture, at the time I didn't even know what one was. I thought I had seen a shooting star, I've seen tuns, but had ever seen one green like that...

All things entering/re-entering the atmosphere move quick, especially meteor's, so getting a picture is admittedly very difficult. Further you need to have the camera set up to take night shots and that requires a tripod, a slow/open shutter speed, aperture as wide as you can go, and a fast ISO. However you did see a "shooting star" thats the colloquial name for a meteor sighting. As I said above the green colour is not unusual at all.

I went to look it up on the interwebs, and found out it was more likely that it was military activity....

I think you meant to say internet but no matter. As for it being likely military activity, pure rubbish fantasy by someone leading you astray. Exactly why would it have likely been military activity? Did the person who wrote what you read provide an excuse for it, or did you just believe it without questioning it? Better still just post the links here so all the member's can have a look. You have to realise that there are a lot of nut cases on the web who write fantasy and lies in order to make people either believe there delusions or try and gain friends or respect that they think they dont get in the real world.

I know you are young and haven't seen a lot of things yet and it is good that you are questioning what you see but in time you will learn to fine tune your BS filter and learn when to question. In the meantime how about you have a look at some pictures and see if you can narrow down the shape of the helicopter and get back to us with some answers to the questions I suggested. Also try and post a link to the claim that the meteor was suspected military activity and Im sure a few of us here can dig into it.
