Eyes always above
Without press access to see the demolition firsthand, it fell to a camera hundreds of miles above the White House to see what was really happening at the East Wing. Planet Labs released an image taken Thursday morning from one of its SkySat satellites showing the 123-year-old annex leveled.


What became known as the East Wing was first constructed in 1902 and was then rebuilt in 1942 during the Franklin Roosevelt administration to create more office space and provide cover for a bunker during World War II. In modern presidencies, the East Wing was typically home to the first lady’s staff.

Planet Labs, based in San Francisco, operates a fleet of hundreds of small Earth-imaging satellites mapping the planet every day. The company sells its imagery to commercial customers and the US government, including intelligence agencies, which use the imagery to augment the surveillance capabilities of more exquisite government-owned spy satellites.

The SkySat satellite used for Thursday’s examination of the White House flies at an altitude of approximately 295 miles (475 kilometers). It can capture imagery with a resolution of about 20 inches (50 centimeters) per pixel. Planet Labs owns 15 SkySats, each with three overlapping 5.5-megapixel imaging sensors fitted under a downward-facing 14-inch-diameter (35-centimeter) telescope, according to the company.
