Note 1

You don't remember the impact, it was all just a blur...

Where has everyone gone? The plane was full in what seemed just 2 seconds ago...

You were in the air, enjoying the perks of first class...It's all blank.

Over the hill you notice a small hatch in the ground. 

It appears bolted shut for now.

You wonder if you will be able to get it open somehow to find out what the hell is
happening...

The flight manifest mentions something about waterproof cargo...
