If that's firing missiles, GAPAN are okay to fire missiles at me, and while they do, I'll sip a cool Gin & Tonic sat by the pool-side!
It also looks like you have answered you own question; GAPAN have upset the BMAA by trying to encourage them to accept the NPPL aircraft rating revalidation and renewal proposals put forwards by the NPPL Steering committee.
If The CEO of the BMAA is also on the managment committee of GAPAN, then for GAPAN to issue such a statement, without all the committee members agreeing for it to be issued, does seem a little odd. But if this is the case, I'm more interested as to why the CEO of the BMA is on the Board of GAPAN. This isn't a case of "jobs for the boys"?
If the proposal is accepted, surely the BMAA will be in charge of the BFR arragnements anyway, and can make them as cumbersom or slick as they wish?
