We all know the composure+afterburners combo to get a focus twice a game. Does it actually work though? From the RR:
Paying Costs
A ship can pay a cost for an effect only if the effect can be resolved.
For example, GNK “Gonk” Droid’s ability says “Action: Spend 1 charge to recover 1 shield.” The ship cannot spend the charge if it has no inactive shields.
So if you fail the afterburners action, is the effect resolved or not? Because if it's not, then you can't spend the charge and use composure. What am I getting wrong?
For further reference:
Afterburners
After you fully execute a speed 3-5 maneuver, you may spend 1 charge to perform a boost action, even while stressed.
Composure
After you fail an action, if you have no green tokens, you may perform a focus action.

Q: Which effects are abilities?
A: An ability is text from a card a player controls (such a ship card, upgrade card, damage card, remote card, device, condition card, etc).
Q: When is the cost for an ability paid?
A: The cost for an ability is paid when the ability is resolved.
An ability cannot be added to the queue if its cost could not be paid at the time it is added.
If an ability's cost cannot be paid when it would be resolved from the queue, the ability is not resolved and is instead removed from the queue. The ability's cost is not paid.
