Why was orginal Flight 175 flight plan far south of normal route to LA?

[philb]

Flight 175 took off from Logan at 8:14 AM, 16 minutes late and around the time Flight 11 lost contact. At 8:42 Flight 175 switched off its transponder, and veered off-course flying first southward, and then turning north to attack the World Trade Center.

The USA Today graphic is interesting because it shows Flight 175's planned route taking it close to New York City and well south of the most direct route, reducing the distance and time it had to traval off-course to reach its target. This is curious given that Flight 175's flight plan was presumably not filed by hijackers.

I thought Fl 175 was direct to LA and would have taken the most direct route. Did it have a hub stop somewhere that explains the strange flight path?

1. Planes rarely fly the most direct route...

For a few reasons:

1) There are specified departure routes out of every major airport. These funnel the departing aircraft into defined corridors for 60-150 miles to aid in their transistion to high-altitude flight. (there are also arrival routes that do the same thing in reverse).

2) Airline dispatch takes prevailing high-altitude winds and weather into acount before filing the flight plan. These are frequently not straight lines.

3) ATC may change a flight's routing due to weather or traffic concerns.

2. Very good point

And to verify it, we could observe recent Boston-LA flights on the flight explorer.

The flight plan has also an almost 90 degree egde over New Jersey. Very strange.

3. predetermined interval

I think 175's flight path was determined by its timing coordination with Flight 11. The perpetrators probably had an exact timing sequence between the two flights. Flight 175 would crash into the South Tower at a specific amount of minutes after Flight 11 crashed into the North Tower.
