It’s not currently possible to load the full experience (weather, time of day, disabled features, etc), but it’s certainly possible to load old flight plans if you’ve saved them previously. I know the Japan tour is available (link here: Japan Tour Flight Plan For those Who Missed It ), but I haven’t seen the East Coast one. I tried to upload it just now but the site blocked me from doing so because I’m new. Not sure what the minimum post count is but I’ll keep trying.
May be worth looking for anyway.
