Reviewer 2 does geoengineering

Wake Smith explains two recent papers on aviation to @geoengineering1. The first deals with low altitude (13kms) polar deployment, using existing aircraft concepts. The second deals with deployment at 25kms, which adds cost and complexity over the usual 20kms injection patterns in the literature.
