Thanks for all the kind comments. This video of one of my friend`s first flights, was made with a phone years ago and watching the model fly was more important to me than tracking it on the screen. Here is a link to his edited version ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-p6EIwwefuvY.html Hope you enjoy it
Back in the day, yes, partly. They used a combo of RC models, scale non-flying models, and full-scale (manned) aircraft. Nowadays it's just boring old CGI that never really looks right.
