I figured the song out and the chords weren't up here yet so I thought I'd contribute some knowledge.
This is my first tab, please be merciful!
D
What happened to us (what happened to us)
A G
What happened to something that never was
D G
I'm not a crash landing
D
The DNA has changed old hairs shed
A G
and nails clipped into bathroom trash cans
D G
I'm not a crash landing
D G
I'm not a crash landing
A D G
Let me stay up in your orbit a while
A G D
Let me stay up in your orbit a while
D G
Crash landing
Crash landing
D
Do you sleep with your windows open
A G
Would you watch through mine if you could
D
I just want to say the words to someone
A G
Like I used to say the words to you
D G
I'm not a crash landing
D G
I'm not a crash landing
D G
I'm not a crash landing
A D G
Let me stay up in your orbit a while
A G D
Let me stay up in your orbit a while
D
Good times always getting older
Good times you wish could last forever
Good times always getting older
Good times you wish could last forever
Good times always getting older
Good times you wish could last forever
D G
Crash landing
D G
I'm not a crash landing
D G
I'm not a crash landing
A D G
Let me stay up in your orbit a while
A G D
Let me stay up in your orbit a while
D G
Crash landing
Crash landing
Crash landing
Crash landing
