Our son and his wife are currently in Japan. His birthday is coming up and I would like to send him something useful. He's a pilot. Also, we have a tough time coming up with ideas on what to send him when he's on the boat and what his lovely wife might like. We have asked many times to no avail.
One idea might be a mahogany model of a
VAQ-141 "Shadowhawk" E/A-18G Growler, by
AimHigherJets. Google them for info/prices. I had a model made by AHJ several years ago (see below), and I love it!
Another possibility, is a Lithograph of his Growler all painted up in
VAQ-141 "Shadow Hawk" livery. Lithos come in several sizes, and make great hangings on "I Luv Me" walls, & run around $100+shipping. I don't have the artist's info handy right now, but if inferested shoot me a PM & I'll dig it up for you. The Litho artist is a member of AW, and has a website to see his work.
For mine, he drew up a comparison of the
VA-146 "Blue Diamonds" A-4C Skyhawk I flew in Vietnam some 47 years ago, and the
F/A-18C Hornet the VFA-146 Blue Diamonds fly today (see below)... Titled:
VA/VFA-146 - "Then & Now"! He would love it!
As for your lovely DIL, sorry can't help there.
