After a short scuffle with security Bridgepoint director James Murray agreed to come to the reception to hear the protesters demands - it was made clear that this was the start of a long and sustainable campaign against the airport.
Workers arriving for the day were offered Yorkshire puddings and engaged in conversation, explaining the science of climate change and reasoning why Leeds airport - and all the others - shouldn't be expanded.
Finally a declaration from the people of Yorkshire was read out, a souvenir snap was taken and people peacefully left the building.
To his credit, director Murray took his pudding upstairs with him.
