Did several Arnhem drops and as Omega points out there was always a large crowd watching. I remember one year dropping the TA in winds that were to say the least marginal. However everyone was so keen the drop went ahead anyway.
Doing para drops in a Skyvan in the Oman we landed on the DZ to emplane the next lift. As we waited a 'ginormous 'storm appeared from out of the sea. So we sat there with engines running being battered by the strong wind and torrential rain. Interesting experience !
