Shucks ever since the left wing government took their fighters off them, the New Zealand Air Force has taken to flying transports like fighters.
Few years ago I saw an RNZAF C-130H pull aerobatics over wellington city in tight formation with a Boeing 727-100. Now that was even more impressive.
Please ... Please ... sombody just give them a fighter to play with
Actually reflecting on the question about speed, jets achieve high speed at altitude due to lower air density. Perhaps this 757 was pumping about 400 knots as a guess. That's about the upper speed levels of WW2 fighters
