I had several personal dealings with Rakesh, I respected him and when we came to him with issues and solutions, he would ensure it would happen.
The line hangar in Charlotte was built because mechanics showed him that when the work from GSO was moved to CLT, GSO did the work in a hangar, the mechanics at US in CLT were forced to to engine changes and other work that should be done inside, outside. When Rakesh was shown the data, we got a line hangar built.
I can share a few more experiences, but Rakesh was a people person, its a shame that he left cause of Wolf.
