Wes I very very much disagree. 
This was an high-altitude international flight, so whatever SERA (or you ) thinks about the repeater plans is irrelevant.

Both ARRL and RAC 2m Bandplans still show 146.40 as a repeater input, with reference to checking with local coordination bodies...and no where is it considered "non-standard". 

Quote From RAC 2m Bandplan:
(5) The frequencies 146.40, 146.43, 146.46 MHz continue to be used as repeater inputs in some areas. Consult with your local coordination body.

(6) Thirteen (13) Channels on a 15 kHz channel raster 146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505, 146.520, 146.535, 146.550, 146.565, 146.580, 146.595 MHz.

Therefore I would think anyone planning such a flight would steer clear of such (#5) channels. Instead one might consider one of the 'splinter' channels (#6) if its necessary to operate in this section.(eg:146.415)

However, there are many channels assigned for various packet/digital modes that would be much more appropriate than a simplex (voice) channel.

Its hard enough for packet and APRS users to respectfully carve out a sliver of 2m band space without people plopping their gear wherever and with whatever mode they feel like.
