Fragment of Dejavu walkthrough (Both Endings)

Fragment of Dejavu is ReMind's new point and click puzzle game in which the player's objective is to prevent an airliner from crashing. To do that, you must travel back in time using a time machine and change the course of fate. Why would you do that? Because your girlfriend is a passenger in that plane and she's with a terrorist armed with a bomb.

This game's concept is really good and it is almost like the movie Source Code but instead of train as the setting, it's an airplane. It looks good and all but it feels like it needs to be more complex and it needs to have much more things to interact with. But anyway, I'm not supposed to complain here, I am posting a guide so here is Fragment of Dejavu walkthrough showing both normal and alternate endings.
