The Lockheed C-5 Galaxy is a large military transport aircraft designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin.It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo.

The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The An-225's main landing gear The nose gear of the An-225 Unlike the An-124, the An-225 was not intended for tactical airlifting and was not designed for short-field operations . [ 3 ] Accordingly, the An-225 does not have a rear cargo door or ramp, as are present on the An-124, these features having been eliminated in order to save weight.

A Delta Air Lines flight landed with its “nose landing gear up” at Charlotte Douglas International Airport in North Carolina on Wednesday morning, the FAA says.
A nose-over accident with Polikarpov I-15 bis A replica World War 1 F.E.2 fighter. This aircraft uses a tailskid. The small wheel at the front is a safety device intended to prevent nose-over accidents. The conventional landing gear arrangement has disadvantages compared to nosewheel aircraft. [2]
Anhedral angles are also seen on aircraft with a high mounted wing, such as the very large Antonov An-124 and Lockheed C-5 Galaxy cargo aircraft. In such designs, the high mounted wing is above the aircraft's center of gravity which confers extra dihedral effect due to the pendulum effect (also called the keel effect ) and so additional ...
