I cannot tell you about the engineering but for cockpit:
its done by suun express, responsible for the last selection was watermelon selector Mr. Piggy Dery.a Sah... One of the bigest ass.... in suuun. Failed his initial DLR, initila FO and nearly his upgrade.
But good enough for mr general P.
I hope that Mr. Beckfr... and the new guy from Lutfansa will clean flight ops.
