FAQ's:

Testimonial from a satisfied customer:

" Your shipment arrived two weeks ago, but I waited until today to give you great ratings on eBay since I had a reservation today to take a ride on a B-17 bomber from World War II. I wanted to see what your altimeter would read compared to the one of the B-17. the cockpit altimeter read 2200 feet and your altimeter read 2800 feet. I told the pilot and he radioed to the control tower so see what their radar read, and they came back that he was at the wrong altitude. His altimeter was wrong and yours was correct.
Just thought you would enjoy that story. Once a year Moffett Field here in Silicon Valley has a plane show and some of the planes are available to take a half hour ride. I have always wanted to take a ride on a vintage B-17, and this year I had my dream ride."
