[QUOTE]Just remember. If you see it, it's missed you[/QUOTE
Only if you have somewhere else to go. More years ago than I care to remember, there was a big, unforecast nasty that started off over the Channel Islands. We were coming back to Stansted from Frankfurt when we were told both Heathrow and Gatwick were closed. The approach to Stansted 23 (in those days) was clear, but we could see this huge storm coming from the London area, and getting very close. The only option for a go-around was an immediate 180 turn and head for Norwich. We advised ATC of this, telling them to hell with noise-sensitive areas. We, and one other behind us, landed before Stansted also closed. Sitting in the crew-bus, I watched the sky turn green. The only time I've ever seen that, and I presume it was ionisation?
