May I say, the LCA looks somewhat like a Mirage derivative. How many does the Air Force plan to order? Fancy that! It never occurred to me that planes with triangular wings can look so similar! I think the Air force will get 60 LCAs totally. They already have 40 original Mirage/LCAs from Dassault, ...

In continuation to the AEW&C post, ... I do wonder why ELTA are pushing for the G550 when we already have the Phalcon, and when the indigenous one is blazing through. I suspect that they are aiming it for the Indian Naval reqts in case the P8I doesn't come through, or for the tech, if it does. ...

OK.... report on AEW&C Thanks a lot Prasad for getting this report through. One of the best! Here are my questions .... Now, an amazing aspect that hasn't been noted is that this sensor will also have a limited elevation coverage of 10-17 degrees, which i think does not exist on other present d...

Some random thoughts on AI-09: That is an excellent account of on the side vignettes... 5.

Yes! But I have got to accept that people at the ISRO stalls where goons! They didn't know anything and were reluctant to answer (i.e if they knew anything) on Indian manned mission. And the posters too had nothing on mass fraction. But I was surprised that the poster mentioned CE20 as Mk-III upper...

Well, parachute is the best re-entry shape of all. That's how I assume Antrikshyaan Mk-1 will descend, when it goes to orbit.

Check this out http://en.wikipedia.org/wiki/Atmospheric_reentry. Parachutes will work once it has slowed down enough! In lower atmosphere!!

disha, well after that Australian HyShot test at Woomera, it sounded like Indian scientists wanted to replicate that feat, as it was done rather cheaply. So ISRO/DRDO would likely do something similar, mounting a scramjet engine onto a rocket. Woomera HyShot was at a very small scale. Also the scra...

Because Indians lack self-confidence and do not like to think critically (especially when following the white man blindly will get them promotions).

I think ss_roy is talking about the difference in burn time of the solid stage and the LSBs.

So for the last 60 sec the weight of the empty solid...

Ananth,
I went through that article. It still does not in any way support the assertion made about Geelani being a paid agent of RAW.

Maybe he is not a *paid* agent, but a *special* agent for RAW. Maybe an agent with a requirement to be probed specially!

We do not have the logistics to support 120,000 troops in Afghanistan. Finally, 120,000 troops in Afganistan only makes sense if they travel through Pakistan (turning it into kabristan as they stroll through, eliminating all vermin in sight). And we do not have the ability to do that either. Happy ...

disha

The idea is pretty tempting but can't be done unless a direct supply route is available which means a free pro-India/western/democrazy state of Baluchistan is a prerequisite. Even after a safe supply line it would take a Genghis khanish brutality to accomplish anything in that shithole. An attack w...

Sounds more like wishful thinking from people who could not keep quiet anymore - whether Indian military types or goras. Instead of dealing with camps within striking distance in PoK, we send troops across to a neighbouring country to fight and die for the Americans. Hopefully we will earn brownie ...

disha

But tell me detractors, why would this be a bad idea if we could get logistics set up right. OK maybe not 120,000 as planned - but 45000? 1) Is the idea bad because Indian troops will not be Muslims by and large? 2) Is it bad because Indians have no sense of history? 3) Is it bad because we are jus...

The scenario mentions Army Aviation guys. They do not operate LCAs. Moreover you do not need Il-76 / An-32 to transport LCAs. They can get there under their own power.

To others who worry about accidental deaths: We are not talking about a society where everyone carries a gun.
