Andretti had hired personnel away from other Formula 1 teams before FOM put the kibosh on their bid to join the grid.
Andretti had hoped to join Haas in representing the stars and stripes in the paddock as the proposed 11th team on the grid, and hopes were high after they had been given the go-ahead by the FIA late last year.
Fronted by former F1 driver Michael Andretti, the team have become a successful part of many other motorsport series, including IndyCar, Formula E and the IMSA series and were poised to join the fastest series of the all, subject to FOM casting their eye over the commercial viability of adding another team to the grid.
According to The Athletic, behind-the-scenes efforts were well underway, with work commenced on a car model in the wind tunnel. A satellite base at Silverstone was established, housing a workforce of 120 dedicated individuals driving Andretti's ambitious - and ultimately futile - foray into Formula 1.
Andretti made key signings
“It’s a team that wants to do it properly and wants to win,” said Andretti's newly-appointed technical director Nick Chester.
“You don’t want to be anywhere that doesn’t have that ethos. As I started talking before I joined, the resource behind it, the effort that was going to go behind it to make it win, just made it very, very attractive.
“We’ve had people joining from Red Bull, Ferrari, Mercedes, McLaren. They all wanted a new challenge. It’s that real potential to shape departments which is very attractive.”
