My First Flight (The real bird’s-eye view)

Ha ha !!!!!!!!

Memories are still fresh !!!!!

it's been so long as a fresher I joined an IT company as a software engineer at Bengaluru. I used to trip between cities via bus or train.

I was waiting for a chance to travel by flight which never happened.

One fine day I got a call from my manager that I would be travelling to Chandigarh for some project work and I need to report in a week time.

Next day was thinking about how to travel it’s almost 2500 km travel and I received a call from my manager asking travel details and I informed him of the concerns.

Manager giggled and said that I would be travelling by flight and expenses will be taken care of. I was so happy and bit nervous to travel by flight as I need to travel alone and that was my first time to travel that distance that too by flight.

Somehow I managed to book a flight and I reached the airport And the entire environment was new to me the boarding protocols and the security checks.

I got my boarding pass and went to that lobby and I was told that my flight will departure in next half an hour and I was waiting for that flight.

Cleared the checks and the moment I entered into the flight all those nervousness increased and my heart started pumping. got a window seat took few pictures through flight windows asked someone to take a pic of mine.  

Somehow I got adjusted To the environment everyone on got settled on their seats and Air hostess started instructing the safety instructions. Caption introduced himself and announced details about the journey.

Flight moved slowly on the runway and gradually increased speed OMG it was an awesome feeling the flight airborne. It was a smooth take-off and I saw the city from the sky the real BIRD’s-EYE view. 

I took snaps of city, clouds, Blue-sky just enjoyed every minute of flying journey continued for an hour and the flight landed with the thrill of its own and I got down from the flight. Yeah, that is one of best first-time experience of my life.
