See the $6 million Lockheed-funded helipad the White House is getting to protect its lawn from Marine One

The White House is constructing a permanent granite helipad on the South Lawn, funded by Sikorsky Aircraft (a Lockheed Martin subsidiary), to accommodate newer, more powerful Marine One helicopters that damage the grass. President Trump stated the $5-6 million project will protect the lawn and noted Sikorsky's financial contribution due to underestimating the helicopters' power.
