The wingspan
Wingspan
The wingspan (or just span) of a bird or an airplane, is the distance from one wingtip to the other wingtip. For example, the Boeing 777 has a wingspan of about 60 metres (197 ft); and a wandering albatross (Diomedea exulans) caught in 1965 had a wingspan of 3.63 metres (11 ft 11 in)…

In 2007, the United States Air Force was seeking to upgrade Air Force One by replacing the VC-25A (two heavily modified Boeing 747-200Bs acquired in the late 1980s). In 2009, Boeing was reported to be exploring a 747-8 proposal, along with a Boeing 787 Dreamliner variant. In January 2015, the Air Force announced the selection of the 747-8 to replace the aging VC-25A for presidential transport. U.S. Air Force Secretary Deborah Lee James said, "The Boeing 747-8 is the only aircraft manufactured in the United States [that] when fully missionized meets the necessary capabilities established to execute the presidential support mission..." In July 2016, Boeing received a second contract for pre-engineering and manufacturing development (EMD) risk-reduction to address "system specification, the environmental control system, the aircraft interior, the electrical and power system and sustainment and maintenance approaches."

How much runway do private jets need?
Comparably, commercial aircraft require significant runway space to take off or land, typically a minimum of 4,500 feet and a max of up to 13,000 feet or more. The harsher the weather and thinner the air, the longer the runway needs to be for a safe take off and landing.
Why is the runway shorter at higher elevations?
The lower the airport elevation, the shorter the runway needs to be. This is because the air is much thinner at higher elevations.

What does it mean when an aircraft travels at a greater speed and for a longer distance to achieve a
This means the aircraft must travel at a greater speed and for a longer distance to achieve a safe takeoff . The same principles that apply to elevation also apply to temperature. The higher the temperature, the lower the atmospheric pressure, the longer runway needs to be.
How fast is a cruise?
Normally at cruise, the speed is closer to mach .85 / 500 knots true airspeed, which is around 925 km/h or 575 mph). The optimum cruise speed depends on a number of things, amongst other things fuel price, airborne airframe cost, airport curfews and more.
Overview
The Boeing 747 is a large, long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States. After introducing the 707 in October 1958, Pan Am wanted a jet 2+1⁄2 times its size, to reduce its seat cost by 30% to democratize air travel.
