The other two emulsions might be though.
Backwards compatibility seems to be sacred in this kind of 
military/bio aerial photography, so 2443/E4-EA5 might be around for a 
long time to come. Long time military contracts come to mind as well, 
as was also mentioned in that new E6 rumour some months ago.

Please do.
There are several other bio/agricultural-related members present on 
this list, but experience with 70mm is still scarce. 

The inconsistency of such a daylight 70mm loader (or even 35mm
daylight loader for that matter) in case of HIE has crossed my mind
before, a great bummer for a gearhead like me....8-))
