Well Nonny, i think the Pilots in their 146's are a bit peculliar about their brakes.... something to do with Hot brakes ?? Possibly the one that was slowspediting had to use his or her brakes on landing a tad over regular? therefore was afraid to reheat them on an expedite B/T... and there fore having to wait before T/O so they cooled..?
It is just a senario... could be just .... Anything.
