Some people are protesting a proposed expansion of London Heathrow. [I saw some protestors of the Heathrow expansion with signs](http://www.airportwatch.org.uk/2019/03/severe-impact-of-3rd-heathrow-runway-on-residents-laid-out-in-high-court-hearing/) that read "Stop 700 more planes a day".

[Greenpeace tells me](https://greenwire.greenpeace.org/uk/en-gb/system/files/uk/document/107991e6-2899-42dd-aea8-724d3164da14.pdf) "A third runway would mean 700 extra planes
a day using Heathrow."

Are 700 more planes a day expected to fly because of the Heathrow expansion, as the signs imply?
