As a good pilot, one must keep revising your basics regularly. Some of the stuff not easily available elsewhere could be read in the Aviation section. If you wish to enhance your professional skill and overall capability, try and understand your true composition; read the Human Spiritual-science in the Service page. You will find your performance improve in every aspect of your life as you climb towards reaching that point (spark) from where all the energy flows into our system. I regret I would not be updating much in the Aviation side as I am deeply engrossed in various efforts to result a much needed transformation for our planet today; I am trying hard to build a new India, a great India!
