I live about an hour southwest of Ft. Worth Texas and there have been these fighter jets flying over our house all day. What is going on? Would it be because of the hurricane? Why would fighter jets need to go check out the hurricane? This is VERY unusual for this area.

They are moving jets and aircraft out of the path of Ike and it's projected path. It is more of a precaution and nothing to be worried about.

Actually the jets were flying south.

Maybe they were headed south initially along a flight path? Generally, planes don't fly directly from A-B, they have to follow corridors. Not saying its not anything out of the ordinary, just offering a possible explanation.

1) Hurricane move to south of texas
2) Planes move north from path of hurricane.

Considering the location and the timing, it was probably due to Hurricane Ike. Just because they were going south doesn't mean they are going to end up south. That may have been the most effective passage to avoid conflicts with commerical flights.
