Virgin Blue 737 Hump

[Troy P]

Hi there,

I am new to this forum and as an absolute novice, this may appear to be a dumb question.

I have noticed that there appears to be a hump on top of Virgin Blue's 737's that don't appear to be on any other 737 belonging to any other airline.

Could someone please explain what this is?

Thanks
