Important Observation About JetBlue Landing

Next time try a series post.

Yeah, the painted strip might ignite the whole LA basin.

The sparks were caused by friction of the metal parts of the nose gear contacting the cement. I don't think the paint on the runway entered into it.

Good Point, Is there such a Non Flammable Paint the will withstand all those TA/L and be cost effective ?????

Very good observation. I too noticed it and mentioned it to grandpa. He said the paint was burning even though the commentators kept saying the tires were on fire. It was quite obvious.

Here is the video


Watch the paint stripe

Sure it did. Paint is flammable.

I was under the impression that emergency services had sprayed down the tarmac w/ anti-flammatory chemicals, and that these bursts of sparks were when the tire stem hit less saturated areas.

check the video, then make your comment.

This may also ahve been the ground up magnesium of the wheels being scattered and burning and maybe just coincidental that the wheels/gear was centered over the stripes.

[satchmodog9]

You sure it wasn't the other way around that the paint stopped the sparks and the landing gear only sparked when it hit bare tarmac?

[spycatcher]

Stripes were flaming up alright

[GrandmaPatriot]

Did you look at the video? Check again.

[Iwentsouth]

Yeah watch the video. I think he mas made a good observation.

If the wheel is made of aluminum, then the fire was probably caused by a combination of aluminum dust and rubber which burns like a blow torch. These just happen to be two key ingredients for making certain types of rocket fuel.

I agree-- the nosewheel wasn't exactly on centerline-- it wasn't paint on fire at all. It was sparks from metal on concrete, sparks that appeared to flare up and then subside, probably in time with the weight of the aircraft shifting up and down on the nosewheel assembly as the aircraft slowed.

Notice he used most of the runway that was about 10,000 feet long-- I don't think he used any brakes, since the weight would have shifted forward onto the nosewheel, causing the gear to dig in and making it more likely for the nose gear to collapse.

He did an outstanding job, all considered.

Watch the video and keep in mind at what points the flare-ups occur and when they stop..

It seems to be all related to whether the gear was on the painted portion of runway or the unpainted.

It was like a light switch turning on and off.

I'm not sure the color was right for magnesium.

The amazing thing to me is that the front strut still functioned after all that -- you would think the heat would boil the fluid and seize it.

lol!
