A transport device such as an ISO container that is adapted to be transported by air or surface transportation. The transport device includes a base, a plurality of movable ISO corner blocks movably coupled to the base, and a plurality of adjustment mechanisms. Each adjustment mechanism is adapted to couple a respective corner block to the base and to selectively move the corner block with respect to the base between an air transport position, wherein the bottom surface of the corner block does not extend beyond the bottom surface of the base, and a surface transport position wherein the bottom surface of the corner block is located below the bottom surface of the base. The base includes a plurality of roller plates that form the bottom surface of the base and that are adapted to engage rollers of an aircraft cargo handling system. The transport device also includes detent rails that are removably attached to the base. The detent rails includes tabs and detents that are adapted to cooperate with an aircraft cargo handling system to releasably secure the transport device in place within an aircraft.

What is claimed is: 1. A transport device adapted to be transported by air or surface transportation, said transport device comprising: a base; a movable corner block movably coupled to said base; and an adjustment mechanism adapted to selectively position said corner block with respect to said base, said adjustment mechanism adapted to selectively move said corner block between an air transport position and a surface transport position, said adjustment mechanism including a leg having a first end coupled to the corner block and a second end coupled to a selectively rotatable shaft such that rotation of said shaft moves said corner block along a translational axis to a selected position with respect to said base, and a connector member coupled to said leg for conjoint movement with said leg and said corner block along said translational axis, said connector member including a rotatable ring and one or more locking pins coupled to said ring such that rotation of said ring conjointly moves each said locking pin between a retracted position and an extended position, said locking pins adapted to prevent movement of said leg and said corner block along said translational axis when said locking pins are in the extended position, said locking pins allowing movement of said leg and said corner block along said translational axis when said locking pins are in said retracted position. 2. The transport device of claim 1 wherein said base includes a first end and a second end, a first side rail and a spaced apart second side rail extending from said first end to said second end of said base, and one or more roller plates extending from said first end to said second end of said base, said roller plates located between said first side rail and said second side rail, each said roller plate including a generally planar bottom surface adapted to engage rollers of an aircraft cargo handling system. 3. The transport device of claim 1 wherein said base includes a first side rail and a spaced apart second side rail, a first detent rail attached to said first side rail, said first detent rail including a first leg having a plurality of tabs and detents, and a second detent rail attached to said second side rail, said second detent rail including a second leg having a plurality of tabs and detents, said tabs and detents adapted to cooperate with an aircraft cargo handling system to releasably secure said transport device in place within an aircraft. 4. The transport device of claim 3 wherein said first detent rail is adapted to be removably attached to said first side rail, and said second detent rail is adapted to be removably attached to said second side rail. 5. The transport device of claim 3 wherein said first detent rail includes a third leg located generally perpendicular to said first leg, said third leg adapted to be removably attached to said first side rail. 6. The transport device of claim 1 including a plurality of corner posts, each said corner post including a first end and a second end, said first ends of said corner posts being attached to said base, a plurality of said movable corner blocks, each said movable corner block being located adjacent said first end of a respective corner post, a plurality of said adjustment mechanisms, each said adjustment mechanism adapted to selectively position a respective movable corner block between an air transport position and a surface transport position, and a plurality of stationary corner blocks, each said stationary corner block being attached to said second end of a respective corner post. 7. The transport device of claim 6 wherein each said movable corner block and each said stationary corner block includes a first side wall including a first aperture and a second side wall including a second aperture. 8. The transport device of claim 6 including side walls extending between said corner posts and a roof such that said transport device comprises a container. 9. The transport device of claim 6 wherein said adjustment mechanisms are adapted to respectively move their associated movable corner blocks to a selected extended position which is located further from said air transport position than said surface transport position is located from said air transport position, whereby said adjustment mechanisms are adapted to respectively position said movable corner blocks with respect to said base such that said base may be supported by said movable corner blocks in a substantially level position. 10. The transport device of claim 1 wherein said base forms a pocket, and wherein said movable corner block is located substantially completely within said pocket when said movable corner block is located in said air transport position, said movable corner block being located at least partially outside of said pocket when said movable corner block is in said surface transport position. 11. The transport device of claim 1 wherein said shaft of said adjustment mechanism includes a first end, a second end and a central axis, said movable corner block being coupled to said shaft, and said adjustment mechanism includes an actuator for selectively rotating said shaft, whereby selective rotation of said shaft moves said movable corner block along said translational axis to a selected position with respect to said base. 12. The transport device of claim 11 wherein said actuator comprises a motor operatively coupled to said shaft, said motor adapted to provide selective rotation of said shaft about said central axis of said shaft. 13. The transport device of claim 11 wherein said adjustment mechanism includes a housing having a first end and a second end, said first end of said housing being attached to said base, said second end of said shaft and said second end of said leg being located within said housing, said second end of said shaft being rotationally coupled to said housing. 14. The transport device of claim 13 including a corner post attached to said base, said housing being attached to said corner post, said corner post and said base forming a pocket adapted to receive said movable corner block when said movable corner block is located in said air transport position. 15. The transport device of claim 14 wherein said actuator includes a drive member in operative engagement with said shaft, whereby rotation of said drive member provides rotation of said shaft about said central axis of said shaft. 16. The transport device of claim 15 wherein said corner post is generally tubular and said housing and said actuator are located within said corner post, said corner post including an aperture providing communication with said drive member of said actuator. 17. The transport device of claim 13 wherein said connector member is threadably attached to said shaft such that rotation of said shaft moves said connector member, said leg and said corner block along said translational axis, said locking pins of said connector member adapted to engage said housing in said extended position and thereby prevent movement of said leg and said corner block along said translational axis. 18.
