At the start of the trial, prosecutor Simon Jones told the court: "As events unfolded, the F1 Grand Prix had started and it was under a red flag after a serious accident had occurred at the very start.
"Each of these defendants were present at Silverstone and they were intent on causing a disruption to the race.
"It is not in dispute that five of the defendants in this case - all of them save for David Baldwin - made it on to the racetrack and they did not have permission to be there.
"There is no dispute as to that, and they sat down in front of the ongoing cars - Formula One motor racing cars.
"They will inevitably say that this was done as an act of protest and in order to bring publicity to the cause and demands they make."
Video footage from various camera angles covering Silverstone was played to the jury, as well as personal video statements from five of the defendants recorded a day before the protest, including a claim that the world is "being destroyed for the benefit of a few people".
Mr Jones told the court: "The prosecution say that there was clearly an immediate risk of serious harm being caused. Plainly they could have been struck by fast-moving vehicles with obvious severe consequences.
"We say that that their actions also caused risk to the drivers themselves and the marshals."
McKechnie, who grew up in Weymouth in Dorset, told jurors the group had planned the protest over two-and-a-half months, making it as safe as possible.
He also denied that the action, designed to draw media attention to Just Stop Oil's call for the Government to halt new fossil fuel extraction licences, had been reckless.
McKechnie has a previous conviction for tying himself to a goalpost to disrupt a Premier League football match and was convicted alongside Brocklebank after they glued themselves to the frame of a Van Gogh painting at a London gallery last June.
