Just had a glimpse over at RCGroups. Still three blind men and an elephant. Causby was essentially a noise abatement suit
and did not establish any altitude claims or really anything else. The award to Causby was eventually reduced because the heavy
bombers and fighters quit using the field. The field continued in operation with GA traffic typical at the time. The dimwits also don't
know that the Causbys had lived there for 8 years with the airport operating before the military began using it. The capper is that a
couple of years later subsequent legislation added take off and landing glidepaths to "navigable airspace", the supposed loophole,
though it was obviously part of routine operations even though not previosly spelled out.
