Arrived at this post by chance and it reminded me of an incident back in the 1960’s when I was flying Lightnings in the RAF. The flying programme got underway late one morning because the first pair of aircraft had low tire pressures and had to be changed. The newly arrived 1st line techie was congratulated for his diligence. Wheels on the Lightning were at very high pressure and inflated inside a safety cage where they underwent a leak test for, I think, 24 hours.
When the 2nd pair failed the pressure tests it dawned on the Line Chief to check the pressure guage. Guess what!
