I am not sure I communicated my point very well in my earlier post, so please excuse me while I try again.
An aircraft with less than 2G of thrust can use it's airframe to alter it's course by 90 degrees at 9G of lateral turning force.
A spacecraft with 2G of thrust could vector his thrust 90 degrees and alter it's course by 90 degrees at only 2G of lateral force. The aircraft will make a tighter 90 degree change of course than the spacecraft.
If the spacecraft had the Classic Traveller maximum 6G thrust, it could vector its thrust 90 degrees and alter it's course by 90 degrees at 6G of lateral force. The aircraft will still make a tighter 90 degree change of course than the spacecraft.
Therefore, given the above observations, an aircraft with a 2G engine is more maneuverable than a spacecraft with a 6G engine. Aircraft are simply more maneuverable than spacecraft.
PS. Thank you for the clarification on maximum aircraft thrust. I knew that there were a few aircraft capable of sustained vertical flight (greater than 1G thrust) and I was pretty sure that they were not above 2G acceleration, but I did not know what the exact figures were.
