The Master Pro is an excellent kit, but has some compromises due to its relatively compact size. It is designed as a personal survival kit to be carried on a belt or in a pack. An aircraft survival kit can be somewhat larger and can include some components that there simply isn't room for in a smaller kit, such as more medical gear, some real rations, water and the like, as well as larger and more robust components. The Exploration Products deHavilland Kit is a good place to start, also generally very good quality, though I suggest upgrading the medical portion.

For that matter, either kit would be a good place to start, just depends how much effort and expense you want to put into upgrading and how complete a kit you are comfortable with, based on what gear you carry on your person and your skills level.
