It really don't mather. 1000ft, 2000ft or 3000ft...

Is not like planes fly right above Chicago's CBD. and might risk hiting a building.

orange line is the virtual extension of O'Hare International Airport runway, the landing path.

white line is the distance from airplanes coridor to CBD (5-6miles).

That would be fine if planes took off and landed in a straight line and never turn. Truth is, many flights take a path over Lake Michigan and wrap around the east and north of the city before landing. Also, planes are constantly circling the airport in a metropolis like this.

Are they circling above Sears Tower antenas?

I'm still sure that even at 3000ft is not a problem for airplanes.

They may be concerned that when circling during a thunderstorm or something, they could get lost and crash, or there may be a downburst or something that causes them to lose altitude rapidly. *shrugs*

The same thing happens in Dallas for Love Field (Southwest Airlines Headquarters) the planes are always flying right over Downtown, but they circle around central downtown, sling shooting around the towers. Some times they get so close that from the planes, you can actually see people sitting in there office working (or having sex, that was a chance view though, i took a picture)

The point is, 2000Ft is the law and there is no push or need for that to be changed. I have flown into Chicago a bunch and you do not go in a straight line. you fly North up Lake Michigan and turn left just to the North of downtown. In fact it is the best view of downtown you can get.


I'm sure with some need and some lobbying and such it could be changed but right now there is no reason to. JMO

Unless they drastically alter O'Hare and Midway flight path, holding patterns, landing patterns. Chicago cannot really get any higher towers due to risk of safety. A plane can easily veer 5-6miles off the landing path in bad weather.

And changing the above means possibly large delays at the airports. I have taken many flights that go really close to the buildings near Chicago.

It's not a law, it's a guideline which can be exceeded with the proper permission. It is not the be all end all.

A) Flight paths can be changed.

B) The "law" is not an FAA guideline, it is originally an FCC guideline, believe it or not, concerning radio and TV towers, though you would need permission from both agencies to build taller.

From the FCC:

"Although there is no absolute height limit for antenna towers, both agencies have established a rebuttable presumption against structures over 2,000 feet above ground level. The FCC has a policy that applications filed with the FCC for antenna towers higher than 2,000 feet above ground will be presumed to be inconsistent with the public interest and the applicant will have a burden of overcoming that strong presumption. The applicant must accompany its application with a detailed showing directed to meeting this burden. Only in the exceptional case, where the Commission concludes that a clear and compelling showing has been made that there are public interest reasons requiring a tower higher than 2,000 feet above ground, and after the parties have complied with applicable FAA procedures, and full Commission coordination with FAA on the question of menace to air navigation, will a grant be made. See 47 CFR § 1.61 Note.

The FAA presumption against construction of structures over a certain height is set forth in the FAA rules. A proposed structure or an alteration to an existing structure that exceeds 2,000 feet in height above the ground will be presumed to be a hazard to air navigation and to result in an inefficient utilization of airspace and the applicant has the burden of overcoming that presumption. Each notice submitted under the FAA rules proposing a structure in excess of 2,000 feet above ground must contain a detailed showing, directed to meeting this burden. Only in exceptional cases, where the FAA concludes that a clear and compelling showing has been made that it would not result in an inefficient utilization of the airspace and would not result in a hazard to air navigation, will a determination of no hazard be issued. See 14 CFR § 77.17(c)."

J. P. Morgan ends mortgages for overseas buyers
By: Eddie Baeb Aug. 29, 2008

(Crain’s) — J. P. Morgan Chase & Co., which had been part of efforts to market the Chicago Spire overseas, earlier this month eliminated its program that made mortgages to foreign buyers.

The move by J. P. Morgan, which offered mortgage loans to prospective foreign buyers in the planned 150-story Spire, was among others recently instituted by the New York investment bank as part of efforts to tighten its mortgage lending practices, says a company spokesman...
