Boeing has had six years of production problems, safety issues, delivery delays and unhappy buyers of its aircraft. But President Donald Trump’s anger at the delays for the next generation of Air Force One jets could result in a huge blow to what remains of the company’s prestige and finances going forward.

Boeing CEO Kelly Ortberg on Thursday said Elon Musk, the head of its space business rival SpaceX, is "helping us a lot" in navigating through delays in delivering Boeing's Air Force One presidential jet.

It can attain altitudes of 45,100 feet, speeds of up to 630 mph, and a range of up to 6,800 nautical miles – if no refueling is available. Unlike civilian 747s, Air Force One is equipped with mid-air refueling capability. It can stay aloft indefinitely, provided a tanker is available and the plane does not suffer a mechanical issue.
