according<\/a> to the Federal Aviation Administration.<\/p>\nOn Sunday night, however, LaGuardia\u2019s surface detection system failed to notify controllers of the looming disaster on runway 4, NTSB Chairwoman Jennifer Homendy told reporters. Quoting the analysis from a replay of the detection system, Homendy said the system did not alert controllers because the fire trucks on the ground were in close proximity and were \u201cmerging and unmerging near the runway, resulting in the inability to create a track.\u201d<\/p>\n
Homendy said the truck that collided with the jet did not have a transponder. While surface detection systems can track vehicles without transponders, Homendy said that transponders help the effectiveness of the system.<\/p>\n
\u201cIn order for ASDE-X to work well, you have to know where ground vehicles and aircraft are, and in this case, that ground vehicle did not have a transponder,\u201d she said. \u201cAnd it would\u2019ve been helpful \u2014 when you have a radar target, it does not provide you with the information that you need like it would for an aircraft as a controller.\u201d<\/p>\n
The NTSB chairwoman added that when investigators watched a replay of what the detection system showed controllers, it did not show any \u201cblobs\u201d\u2014 which represented the emergency vehicles \u2014 move in front of the plane, indicating that the system failed to accurately track the fire trucks.<\/p>\n
The NTSB also revealed on Tuesday that there were two controllers on duty at the time of the deadly crash, which Homendy said was consistent with normal operating procedures for many airports, including LaGuardia, for the midnight shift. The midnight shift at LaGuardia begins at 10:30 p.m. and ends at 6:30 a.m. The Air Canada jet crashed into the fire truck at approximately 11:40 p.m.<\/p>\n
The NTSB chairwoman said that officials would look into whether it \u201cmakes sense\u201d for LaGuardia to operate with just two air traffic controllers on the midnight shift, or if the airport should change its procedures.<\/p>\n
Homendy cautioned reporters about \u201cpointing fingers at controllers,\u201d arguing that there are many factors officials still must investigate before pinning the blame on air traffic controllers. Audio from the air traffic control tower revealed one of the controllers saying that he \u201cmessed up\u201d after the collision. Another controller replied, \u201cNo man, you did the best you could.\u201d<\/p>\n
According to the NTSB, 25 seconds before the crash, truck 1 requested air traffic controllers to allow it to cross runway 4 as a group of emergency vehicles were responding to an issue with another jet on the tarmac. Twenty seconds before the end of the radio correspondence, \u201cthe tower cleared truck 1 and company to cross runway 4 at Taxiway Delta.\u201d<\/p>\n
When the truck was cleared to cross, the Air Canada jet was 100 feet from the ground as it approached runway 4. Nine seconds before the radio transmission was cut off, however, the air traffic controllers told truck 1 to stop, just one second before the Air Canada jet\u2019s landing gear was heard touching down on the runway.<\/p>\n<\/div>\n
