Let me check next weekend Joe. I will see if Mark is around to ask. He has had his share of off and on groundings over the last few years, most of them to do with wing separation. But when I saw him in June, all was a go and he was flying.
Here are a couple of shots of Mark's Mentor, taken by me in June of this year.
I love taking pictures of airplanes (like I needed to tell you guys that!) and when they are being discussed,it's always good to throw a pic in just in case someone doesn;t know what they look like and are afraid to ask.
