Each of them have over 200 flighs since this spring. I'm retired so I fly when ever I have a day where the weather permits.
I was just wondering what's that yellow thing on them and I can't make a close-up on your pix...so that's what they are,that's a very good idea and I might try that too.Thanks ! Have a safe flight always ....
