Nearly 11PM and no sign of stopping flying over Buitenveldert. The use of Buitenveldertbaan has become a notmal sense now, day and night. Last year the use if this job stay at around 4-5% per week, during heavy weather went up to 10% and this already caused alot of nuisance and complaints. Even after the close of Aalsmeerbaan, one month ago, it was roughly 20%. And just last week, 1/3 of total flight. I am looking forward for this week report, probably go up to 1/2.
