Really? I am intrigued...I've never heard of an aircraft based radar that can measure vehicle speed....
OP. Two comments-
DO NOT view your court date as an opportunity to get to the bottom of this... just proving they were sloppy or imprecise in their comments and ticket content will not serve your cause. (Or even if they were testing an aircraft and comparing it to your radar measured speed.) You need it to find out the details of their case and THEN decide on a path to undermine their 'facts'.
Proving your speed is 72 and not 80- which seems to be an issue for you- will result in Guilty. I cannot tell you how many times I hear people outraged at the officers estimate then turn around and essentially admit to a speed that is, in and of itself, over the limit. (Like every time I am in traffic court!)
What the officer said to you and your witness is not the facts of your case...the facts will be what is in their statement, and it would not surprise me at all if the story that day and the story on the ticket, are different. The court will believe what is on the officers sworn statement and assume you and the passenger are lying. Unless it is corroborated by, say, video!
Oh, and and if he writes or testifies "The driver stated he was driving 72MPH" they will also accept that as fact.
Best of luck- you have some great help here.
