Everyone who has a TV or gets a local paper of any kind has most likely heard about FAA plans to divert some liftoffs of planes to fly over neighborhoods such as Summerlin and The Lakes. For a couple years there has been a vocal outcry by these residents over the quality of life in their upscale enclaves, although, at one time flights were common over these areas. Jumping into the fray have been city councilmen, such as Steve Wolfson, and Las Vegas Mayor, Oscar Goodman, vowing to fight the FAA, even to the point of filing lawsuits. In defense of the FAA, the matter is simple: divert some flights or shorten the time between liftoffs. For safety reasons, diverting flights is the best answer. Allowing jets to liftoff too close to previous flights leads to disastrous consequences as seen in the November 2001 crash of American Airlines flight 587 after taking off from JFK International Airport, killing nine crew, 251 passengers, and five people on the ground. From Airsafe.com I found this accident sequence which details the plane's encounter with the wake vortex from an earlier flight which apparently tore flight 587 apart as evidenced by one engine and vertical fin piece which were found separate from the crash site.
"The NTSB calculated that the time between flight 587's liftoff from Runway 31L until impact with the ground was 103 seconds. The flight data recorder (FDR) recorded data for about 93 seconds after liftoff and the cockpit voice recorder (CVR) continued to record information until at or about the time of the plane's impact with the ground.
Based on radar data, flight 587 took off approximately 105 seconds behind a Japan Airlines 747. The FDR indicates that flight 587 encountered two wake vortices generated by JAL flight 47. The second wake encounter occurs about 8 seconds before the end of the FDR data. For the first few seconds after the second wake encounter, the aircraft responded to flight control inputs. Both wake encounters averaged about 0.1 G lateral (side to side) movement. During the last 8 seconds of FDR data, the plane experienced three stronger lateral movements, two to the right of 0.3 and 0.4 Gs, and then one to the left of 0.3 Gs. These lateral forces corresponded in time with rudder movements."
But I imagine that Las Vegas political leaders are more concerned over placating the affluent (whom I picture as attorneys, casino operators, and other business owners, who have made their riches from the tourists who fly into Las Vegas) than the safety of the tourist who, at best, is still a mark for the second largest carnival act in the world, now that Macau is number one. Oscar brags that he can say whatever he wants as he is beholden to no one...well, he got part of that right; he can say what he wants, but I guess he is afraid of alienating those rich and powerful voters who throw the best parties. Political and business leaders in the valley are all for uncontrolled growth and higher numbers at the airport--and roadways--but don't want it to impact any part of their lives other than their wallets and pocket books. However, a lawsuit against the FAA is probably a good idea, as long as they can bring it in Nevada courts, because, if it is heard by the Nevada Supreme Court, it is a guaranteed winner for Summerlin residents, as proved by the recent erroneous decision in favor of Steve Sisolak, UNLV regent (who bought property at the end of one runway in the 1980's subject to one height restriction ordinance already in place, never even applied for a variance through the approved procedure, and won millions of dollars in interest and damages). But, if they would win and a plane falls out of the sky because of too many flights on one path....
