My condolences to the entire Colgan family.
Just a word of advice. If this is the first time something like this has happened to you, talk to your CIRP (Critical Incident Reponse Program) team members. They're trained to help you through a crisis like this.
It helps. It really does.
To further back up what Velo said-
In times like this it's normal to feel bad and feel shocked. You might feel a slightly surreal sense of detachment from your perceived surroundings. Maybe even a bit like life is a movie playing on a screen in front of your face and just swimming around you.
You might also be spiked on adrenaline and anger, or just feel sad, sullen, and depressed. Either way, you feel a little more distant from the world around you than normal.
Stop and take an honest assessment of how you really feel, and then SLOW DOWN.
Times like this make it difficult to understand one's true state of mind, but you may not be as composed as you think you are.
This, unfortunately, is a fairly normal response.
If you feel like this, I strongly suggest you speak with someone- ANYONE.. about how you're feeling. I helps more than you might realize and will benefit not just you but everyone around you.
This goes double for working crews. The additional level of distraction inherent in times like these can be taxing and erode your effectiveness.
Don't be the 'tough guy' that doesn't speak up because you think you can 'handle it'.
I speak from personal and witnessed experience- nobody's that tough. This sort of thing is insidiously subtle and strangely pervasive.
Get it out in the open. Nobody needs to face how they feel alone right now.
