Camp Freddie is spot-on.
The crew of a popular, orange painted budget airline once accused me of flying over their taxiing Airbus at 70ft (they later amended it to 200ft).
In fact I was transiting overhead in clear weather at 600 AAL.
Luckily my GPS data "proved" my case. Without it the observations of two so-called "experienced" aviators would have been difficult to counter.
They said that they were worried in case something fell off my aircraft....
