The shirt is wonderful. Have been in the business for 28 years and will be looking to get the "Retired A&P" shirt next. You could use some of the "My Dad Plays on Helicopters" in adult sizes, not just youth.
I love this shirt! It has an L39 in the background (my husband owns a business working on these: Fighter Maintenance Contracting LLC). I have several of these shirts in different colors and enjoy wearing them. People laugh when they read it since it's true.
