Production hasn’t officially started yet, but Brie Larson is hard at work training for her first flight as Carol Danvers in Captain Marvel. The Oscar-winning actress shared a photo this afternoon, presumably taken at Nellis Air Force Base in Nevada, where she started preparing last week.

Captain Marvel will have most of its production take place in California, but it is very common for Marvel Studios to begin and end principal photography on location for their features. Carol Danvers is a member of the United States Air Force before she gets her powers, so Larson is likely getting ready for the first act of what will be an origin film.

Captain Marvel, directed by Anna Boden and Ryan Fleck, flies into theaters March 8, 2019.
