I am not entirely sure this is what you need, but the standard tool for recording and playing back data from rostopics is rosbag. Please take a look at the rosbag tutorials tutorials for some pointers on how to use it.

I hope this answers your question.

thank you , that help me a lot , just another question : when i use rostopic commands in terminal like : rostopic pub -r 10 /cmd_vel geometry_msgs/Twist '{linear: {x: 0.0, y: 0.0, z: 1.0}, angular: {x: ....} for flying up , there are a way to stop this command ?

The publisher should stop when you hit Ctrl + C in the terminal. This should send the INT signal and kill the node.

when i hit ctrl+C in the terminal nothing is happen for the drone , it's stange , there is another method to use rostopic command for flying up or any other mouvement by way it's will take just 3 secondes ( like when we use command for takeoff or land ) ?

I am guessing this is happening because the drone remembers the last command and continues with that. To stop it you should probably publish a twist with all values set to 0.
