EI-RB does not represent any 'Aer Lingus crowd'.
He has made wild accusations about nepotism and secret hirings at Aer Lingus in the past that were way off the mark.
He recently suggested that posters who were attacking Mannion would all be proved wrong by the great man. So much for that.
I would be certain he is not and never was an EI pilot (a chip?) and I believe he doesn't even work for EI (any more).
