Some years ago, while attending an air show at St Athans with my wife and sons, the weather was threatening–suddenly there was a cloudburst. Fortunately, we were near to a static VULCAN, so we, with a few hundred others, ran for shelter under this massive DELTA.

My son remarked

‘it`s like an umbrella’

to which I replied

‘it must be the most expensive umbrella in the world .’
