He was never with Tejas. Always with LCA Navy. Some people have the passion to fly. Others are deskbound. A certain gent heading Boeing India now is the biggest impediment to LCA Navy Mk2. Any guesses which fighter he would want to see on Indian ships?!!!

Re: HTT-40 Basic Trainer Aircraft: News & Discussions - 08 September 2019

Phillipji HTT40 is too much of an aircraft for most pilots at flying clubs. Hansa would be that aircraft. I dont know what happened to NM5, but that is another aircraft with great potential.

As much as I agree with you, weaponization and surveillance has been a stated goal of the HTT-40 program.

Re: Chandrayan-2 Mission

I am still trying to understand how the lander is intact. For this to happen, it had to slow down considerably from the time of the anomaly. That can only happen if the lander is right side up for most of the rest of the descent.

I am more interested in the final moments now.

We don't use aerial bombing or guns in anti-naxal operations. They won't acquire shoulder-fired SAMs. This is the unstated ground rule. We use Do-228s for recce, and Mi-17s/Dhruvs for CasEvac.

Of course, VL-Astra is very different from QRSAM.

Don't know about the altitude. Without a booster As...

It is unlikely to be a software error. It went into a state that the software did not know to correct from. I was thinking how to simulate the lander on earth.

Why not? You just need something which exerts a vertical upward force of 5/6 times that of weight of the lander. For example, in a tethered experiment, you can use a helium balloon.
