[UI] - Repair agents

:bullseye: What is your suggestion?
Have the repair request happen randomly during handling

:hammer_and_wrench: How would it work in the game?
Sometimes handling happens at random times during operation from the moment the engines stop to last minute/during boarding as it currently is in the game. Would be interesting to have it happen at random times that can happen at any time and different durations. Some times when it happens at the last minute it could also cause delays.

Not suggestion as it should happen often or to the same aircraft/contracts.

:balance_scale: Why is this a good idea?
What improvement would this bring? would bring more realism to the game as it happens the same way for each contract (when it happens) and would be interesting to see how it could affect handling of a contract/aircraft
