May I ask whether Fedex has a reputation for this kind of endeavour? Have they done other aircraft mods in the pursuit of worthwhile business improvements? It reminds me of the efforts Easyjet were putting in to developing volcanic ash detectors on their aircraft, so as to make their operations more immune to eruptions in Iceland.
I'm impressed by the level of effort in both companies; nice to see a clear understanding of the business benefits of technological improvements, and also to see the drive to make it happen for themselves (rather than hope the aircraft OEM does it).
Thanks!
