Should you have a helipad in a residential area?

I don't think we should have a helipad in a residential area because

• It would cause increased pollution form petrol fumes.
• The helicopters landing and taking-off would make a lot of noise.
• The helicopters might crash into the houses in the area. The houses are small and close together, so that if there was a crash, it is likely that several houses would be affected.
