but it will be the nearest aircraft (that may already be in flight) that will be sent from a pool of 23 possible options
There may be a pool of 23 Aircraft but how many of those will be in a 400/800/ANN service at any one time? A lot more than the 3 spare NPAS will have!!!
Then how many out of the ones lift will be off line due to Tech issues?
Not a lot left to play with me thinks?
So the nearest Aircraft that may be flying (In the wrong direction) that could be sent to the task will more than likely be more than the 20 minutes flying time from the job in hand!!
Good planning, NOT
