I was watching the Manchester -Orlando flight's progress on http://www.fboweb.com (a bit sad I know, but we will be on that flight in 21 days!). After circling Datona for 40 minutes, I noticed that it had been sent to Jacksonville due to heavy thunderstorms in the Orlando area. I imagine that would also affect the returning VSo76 flights and maybe have a knock on for tomorrows flights. Don't know if it has affected the Gatwick flights or flights into Sanford.
