I just can't repeat enough, pls do go to Leipzig.
If you are writing from UK Midlands, you don't understand the situation on the ground. Just as an example, the part of BRU I am living in is ONLY getting the trouble of your night flights, not even a... single... job.
On another of your points, you claim using less noisy acft? Well, DHL required 16 mvts for the MD-11, which is up 500% and this is one of the noisiest acft flying today. And I'll tell you - at night (4AM) every acft is noisy. Just come and experience by yourself.
I'll stop here but pls do not hesitate to go to Lepizig. At least we'll be able to enjoy our nights and the greenery not spoiled by taking off acft.
