There are people who say 'aircrafts,' just as there are people who will say 'sheeps' and 'fishes.' Beyond a certain point, as long as you know what they mean, what does it matter?
The really sad part is that these days even 'professionals' in the 'communications' industry can't get grammar, syntax or pronunciation right much of the time...and apparently there are no better-informed higher ups to instruct them otherwise...so much of the public has no 'standard' to go by.
