I have been to kolkata and it was my first flight journey. Though, everyone says it will be a safer, yet I was bit frightened along with lot of excitement. When the time come for take off, my fear dominated my excitement because of the odd sound at that time. I had to have couple of minutes to settle down and feel like I will be safe.
