I prefer the Flash Gordon spaceships which dribbled sparks as Flash pursued the evil Ming—.

Memory moment ! -

Saturday morning at the cinema when I was a kid, (early 50's) watching the Flash Gordon serials each week.

There was also King of the Rocket Men.

Ihave a vhs album ofthe Flash Gordon adventures.
Wife got em for my xmas years back
I have to play them on a 32” screen as the reolution is poor.
As kids,We had a saturday milk bottle cap admission theater which was the highlight of the week
Two serials, a few comedies including the irritating forest song ones and a talent contest
My sis and I won once, playing a clarinet , violin duet
we won $10.00
A small fortune then.

Orbital manoeuvring is pretty interesting. When they tried docking during the Gemini project the astronauts actually had to figure out most of the rendezvous manoeuvring on their own by trial an error. I'd suggest to try the game Kerbal Space Program for a reasonable representation of how to manoeuvre in microgravity. As far as rolling while or before turning, well, people can handle G loads better if they are applied in a specific direction, and it might help a fighter pilot get a better view of the target he's chasing. Probably not a concern in any real space combat, that is unlikely to ever happen in any visual range, but it helps justifying games and movies.

KSP fan here glad to see you mention it Brandano.

Scott Manly is also a good start to understanding the game and some basic/complex space orbital mechanics. Vintage Space also has some good videos with decent explanations.

Was it Neil or John or ?? who wrote the book on Orbital maneuvers?

Historically , the bank to turn was one of the earliest discoveries around 1910
My pattern stuff from the 70s could be setup to be very neutral
Even the better Imac models were pretty neutral with little tweaking.
Earlier-- the Wrights didn't even have a rudder at first- I think Lilienthal also turned by banking--

Well, birds "can" do it .... depending on their translation speed (w.r.t. the airstream), same as with a heli-/multi-copter. That is, when hovering in one place or drifting motionless w.r.t. wind carrying the bird/aircraft along, it is possible to "pirouette" and axially rotate, obviously sans banking!

As a kid I used to slightly marvel at the smart family pet bird getting "boxed in" after quickly flying to the end of the foyer and then axially rotate (yaw!) with no horizontal motion to get out of the situation. And yes, hovering while maintaining altitude normally requires more power than fwd flight .....
