Was at a display this evening (organised event) and we were about 10 miles out to the east of LGW and A/C approaching every 5 minutes and was thinking what the passengers would see and pilots.
I was operating on a flight into LGW at around about 20:30 (or there abouts) and myself along with my colleagues and all the passengers were watching the fireworks on final approach - it really was a great sight to see.
Incidentally, last night, whilst driving home from LGW there appeared to be a massive bonfire right on the approach to 26L - would this not cause a hazard for approaching aircraft if fireworks were being used under the approach to 26L. The bonfire (and any fireworks) would have been no further than about a mile from the runway threshold.
