Square Wheels
An article in a paper today jogged a memory.
Vulcans on QRA used to stand in one spot for days in end. The weight would create the effect of square wheels which gave a slightly bumpy ride on taxying until the tyres resumed their normal shape. While an aircraft could remain on state for 28 days it was the practice to move them every 7 days I believe if there wasn't a practice taxy first.
Not sure what the Blue Steel aircraft did.
