Rough track surface.
Something dragging along the center line about 2 feet back from the nose. And whatever it is, it's metallic and pointed forward. Some kind of small access panel???RetRsvMike
Checking for fuel leaks.
Low-rider driving too fast over speed bumps.
Not enough air in front tires?
Those are skid plates for ground effects F1 cars. They still use them but ride height is regulated now. The Leyton House cars were revolutionary as being about 7/8ths the size of a previous F1 car. No budget and customer DFV's were it's downfall.Spin
I would guess failure of the suspension control systems (air shocks), causing the suspension to bottom out and thus the air-foil parts to scrape.
Too much suspension travel... the sparks are from the undercarriage being ground off.
Thought he was launching flares to foil an IR guided missile?
It's sparks from the titanium skid plates on the underside of the body used to protect the body from dragging when the suspension is compressed to the limit under hard braking.
Nope.Yellow/orange sparks are from steel. Titanium sparks white.
I guess very few people here watch F1 racing. Those are Titanium Skid blocks and plates that all the cars have been using since the 80's this was probably the first lap of practice and car was set too low and springs not stiff enough for the full down force on this part of the Track (180+ Mph) . This is the March-Leyton House 881. 1988 in Adelaide, Australia
