Nor will it be young Alex Rossi's quest to defend his 2016 victory.
It's a decision that's made waves in both the European and United States racing communities.
"Things are getting a little bit better", Brown said.
McLaren Racing is one of the most respected names in motorsports.
Alonso will be back in two weeks' time for the Canadian GP in Montreal, and it will be a familiar scenario when he returns.
One goal Alonso set out to achieve and that he can now tick off is knowing he is as fast as anyone else in an IndyCar.
Regular McLaren drivers Alonso and Stoffel Vandoorne have not picked up any points so far in 2017.
"There is so much change in Formula One".
Other mishaps included a crash on lap 122 that had doctors checking out 1996 victor Buddy Lazier for chest pain, and a five-car crash on a restart from a caution period just 17 laps from the finish.
"I had a little giggle to myself that I was driving a Formula One vehicle again", said Button, who came out of retirement just for this race. This was seconds before the start of the Monaco race, typically the most intense on the F1 calendar due to its narrow road course layout. "It's going to be a long journey to improvement". "There was close to 300 media on the Honda first floor. One of them came through".
"Our vision for motorsport we have three areas of interest", said Basso, who has worked as both an engineer and marketer with Ferrari and Red Bull. But just, you know, waiting (for) the moment. "You have to stay focused on the long-range goals".
The Briton, in his one-off return to F1 to replace Fernando Alonso, admitted it was "horrible" to see Wehrlein's vehicle stuck against the wall. Alonso's performance was applauded by the Indy veterans, given the fact that he is still a rookie on the 370 kmph oval track. "My girlfriend said "you've got to do what you've got to do", he said.
"This is mega-big. I can't imagine how it's going to be", Sato, victor of just one prior IndyCar race, said of the likely reaction in his homeland. Fernando being one of them, and [he] has stated his desire to try and win the triple.
For McLaren, the Indy500 is not an unfamiliar place.
Vettel won this race in 2011.
McLaren will also have an eye on NASCAR's big event, the Coca-Cola 600 in Charlotte, where they are also sure to have a hand in the outcome.
"I struggled a bit with FP2 with the extra grip", he said, "struggled to find my feet, because you have to brake so much later than I'm used to here in Monaco and carry so much more speed".
He has no plans to emulate Alonso in IndyCar - but would consider other options.
"Obviously disappointed not to finish the race because obviously every race you compete, you want to be at the checkered flag", Alonso said. The penalty dropped him to the end of the line, which was 26th place, but he regained track position with strategy and another caution. However, he does believe there are some things F1 could learn from racing series in the US.
But hardcore Indy fans already viewed him as a hero with significant history in their beloved race.
Vonn also had her photo taken with muscular Australian actor Chris Hemsworth, who played the role of daredevil F1 driver James Hunt in the 2013 film "Rush".
McLaren finger prints can be found on every motor racing series from MotoGP to NASCAR to Formula One, where they supply the ECU (Electric Control Units) or the brains for every vehicle on the grid.
