A notable feature was the ability to pivot both fore and aft main landing gear up to 20° from the aircraft centerline to increase safety during crosswind landings (allowing the aircraft to "crab" or roll with a sideways slip angle down the runway). [39] After a trip to a hobby shop for supplies, Schairer set to work building a model.
A Boeing 747-400's main landing gear. Note the toes-up bias angle of the bogies on the wing gear, to ensure correct stowage upon retraction: 707, 720, 757, 767, 787: 10 wheels [1x2]+[2x4] A Boeing 757-200 from British Airways: 777: 14 wheels [1x2]+[2x6] A Boeing 777-200 from United Airlines.
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 B-52 would fly from the continental US, down Alaska’s Aleutian Islands, off Russia’s east coast and down by China and North Korea to a block of airspace off the Korean Peninsula.

From 1952 to 1962 a total of 744 B-52s of all models were built. By January 1971, all thirty-one remaining B-52Cs were stationed at Westover Air Force Base near ...
On 6 November, a B-52B (tail number 53-0382) from the 93rd Bombardment Wing crashed and was damaged beyond repair upon landing at Castle AFB. The aircraft was performing touch and go landings and the latch on the landing gear lever failed resulting in the landing gear retracting while the airplane was still on the runway.
From [1.0 B-52 Evolution] v1.0.1 / 1 of 2 / 01 jul 03 / greg goebel / public domain: The landing gear scheme was unusual and elaborate, and in fact was kept secret during development. The main landing gear was organized in four big twin-wheel trucks mounted in the fuselage. The trucks were arranged in pairs, fore and aft of the bombbay.
