What counts is not aircraft speed, but angular rate.
Easy: aircraft approaching head on, angular rate near zero.
Like this:
Slightly more difficult: aircraft moving fast, but laterally, and at a great distance. Angular rate low.
Really hard: aircraft moving fast and very close. Angular rate high.
Like this:
Steep bank, directly overhead, a few hundred feet above me. D300, 70-200 @ 140mm 1/750th @f8.
Barely fast enough shutter.
There is precisely zero chance the helicopter photo ship was travelling at anywhere near the same speed as Concorde, which in the image is in supersonic configuration.
Especially with a photographer hanging out the door.
