A bizarre incident involving George Russell noted open practice for the Grand Prix of Azerbaijan abandoned after a loose brain casing damaged Williams.
The incident happened with just over 15 minutes in the 90-minute session, and was abandoned with only an hour left on the clock session.
The mound appeared to emerge when Charles Leclerct overturned the roof of the mine on the course between two and three weeks just a few moments before Russell arrived at the scene.
Adding an insult to injury, flat baggage carrying the damaged Williams back to the pit, struck the bridge and leaked a hydraulic fluid on the car.
Then a second crane was needed to lift the container from the rear of the truck after returning to the pit, where it was finally raised clearly and returned to the team.
"I think it's clear from the data, I think it's clear from what anyone can see, there's probably a lot of damage to the floor of the car, and who knows what else," said Clare Williams team deputy chief shortly after the incident happened on the right path.
"It's clear that we will have to wait and see until we return it to see the real extent of it.
"We'll have to wait and see if that chassis is repaired or whether we should go to our third chassis, but it's clearly not what we want.
"But, of course, it's not clear what you would expect from Formula 1, these irrigation systems have to be strained.
"We will choose this with the control of the race."
This is not the first time that a roof ejection has appeared, while Roman Grosjean has a similar incident to the Grand Prix of Malaysia in 2017.
In that case, the failure occurred during the second practice, while the rest of the activities on the track for the day was canceled, as the FIA took full control.
Australian Michael Massey is again the director of the weekend race, his fourth event in the role, with a constant replacement for the late Charlie Witting to be confirmed.
Practice 2 should start at 2300 AEST.
