The shuttle was a little more inherently dangerous...agreed. However, both shuttle accidents would not have happened if the policy makers would have listened to the engineers.

Actually, the dogfighting capabilities of the F-22 are not that extraordinary. It's very good, don't get me wrong, but it's not what you are probably envisioning. Because of the AIM-9X, guns get used more often in the air to ground role now. In 14 years of training, I can count on one hand how many times a fighter…

Current plans are to have parallel developement paths. An Unmanned and a manned version. If the unmanned version is mature by the time it needs to be put in production, it will probably get the go ahead. There are also plans to field both systems at the same time for different purposes. For example, UCAV's are…

I would like to offer alternatives to your comments:

Actually both China and Russia will be fielding (and in the case of Russia, selling) aircraft with similar performance to the F-22 and F-35 in the next couple of years. Actually, the Chinese F-X fighter might actually beat the F-35 into production. So yes, we need to design another one.

I'll never understand the hate for RotJ. It's hands down my favorite SW movie. Here are all the reasons I loved that movie: WARNING: MUCH SPOILERS

Kind of obvious. As soon as I read the 2nd paragraph, I said to myself "yeah, gliding might use more energy, but at least they wouldn't get eaten." I never really thought that the gliding was adapted for locomotive purposes.

There is already an asteroid named persephone. I don't know if this elminates the name for moons / planets.

Holy cow, did we just see a civil, polite disagreement on the internet. Excuse me, I'm going to go and start stockpiling some canned goods.

Ahhh, X-wing. I loved how in many missions (like the cargo container one) you could take out the all the TIE's and actually kill the Star Destroyer. Just get both shield generators and then do loops behind it with the lasers. SERIOUS points!

I had Sprint for 8 years (ended service in 2008). Switched to AT&T for the iphone. Man, what a night and day difference. People that complain about AT&T never had Sprint.

The Hubble telescope is basically a spy sat turned the other direction. Their airplanes don't have a hubble painted on the side...they have a Key Hole spy satellite painted on the side.

I hope not. I use my iPod Nano when working out. I hate using my iPhone since it is so big compared to the Nano. I can't imagine Apple giving up this segment of the market.

We've had a lot more experience in building carriers. Believe it or not, even though one might have the plans, there is still a learning curve to actually building one. The general consensus is that the Chinese plan to use this ship as a test bed to figure out how to build the next one.

The Su-33 Flanker can operate from this class of ship. The Su-33 is a navalized version of the Su-30 MKK that China already has. In case anyone does not know, Flankers are not jump jets and are instead long-range multi-role aircraft in the F-15C class.

I wish people would stop complaining about the lack of accents in Valkyrie. First of all, most of the german actors were british, that is why they had a British accent.

When you see all the missiles frozen in the air, you can definitely see some shells in there as well.

This movie currently holds a 100% fresh rating on rottentomatoes (out of 15 reviews). That's a good start. This movie looks incredible to me, I cannot understand how anyone can say the trailers don't look good.

Dude, the comics continuity is horrible. I don't know how anyone can be beholden to the comic timeline.

There's something else that water is good for.
