Everything you ever wanted to know about the 737 landing gear: http://www.b737.org.uk/landinggear.htm http://www.aerospace-technology.com/projects/boeing737_NG/ Essentially, the outboard tire meets a seal in the wheel well serving the same purpose as a gear door. The slight loss of efficiency is offset by the less complex system and it's associated reliability and maintenance issues. The CRJ has a similar system except the seal is in the form of "Gear Brushes" which are just what they sound like. If the brushes are missing there are performance penalties that must be applied. The gear doors that are affixed to the strut may also be missing.
