"they fly now" is directly out of the lethal weapon guide to action comedy writing. fast paced lines pitching up to underline a dire situation. so i am ok with the line itself.
but they should not be surprised... which shows the poor handling on the world building.
j9ac9k mentioned over at the mando-thread, that he was happy with the visor/helmet having some functionality.
contrast that with the stormtrooper talking into his communicator. yes, i am well aware that luke and han and c3po used stormtrooper comms in ep4.
but it makes no sense. they should have helmet mics. they could have silently upgraded it
