I hope you take this properly because it's meant to help you in the future. This thread is about panning & aircraft photography with the emphasis being to show motion in your photo. The idea is to use a slow enough shutter speed to blur the background (not easy in a photo shot against the sky but clouds do make it possible) & prop blur so we know the engine is running. A smooth pan & a low shutter speed done right is the key to this type of photo. You need to examine the samples posted & think about trying to improve your technique the next time you get an opportunity like that. Shutter speeds of 1/320 & slower are suggested & as you get better with your panning you slow it down another step.
