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.

I don't think the paint on the runway entered into it.

Sure it did. Paint is flammable.

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.
