What equipment and preparations are necessary to shot a picture like this (an in-flight close-up, clearly shot over a large body of water, possibly from a short distance):
This question is somewhat similar to my question asked at Travel half a year ago. But, in that picture plane was captured during final approach, over a city, supposed from some building (actually turned out to be shot from a helicopter).
I assume that using a telescope or shotting from any building won't help much in shooting such picture as above. If not, then what? A drone? Again, a helicopter?
