Flight data within a bounding box

Hello all,

Through the firehose API, is it possible to somehow define a bounding box (like a rectangle on a 2D map of north America) and extract data corresponding to all flights as they enter the box and as long as they remain within the box? Thanks in advance.

Regards,
Satish
