I would'nt blame Marcel, he's just a #anker who wasn't prepared to lend one rappen more to a rotten liability. Lukas of CS maybe because he was on the board.
I blame Otto (d1998) and his board of cronies - panicked into the 'Alcazar' disaster (projected merger with Sabena and KLM), dominated by Moritz, and responsible for the IFEN (in flight entertainment system) fiasco that led to the mass murder of 229 passengers and crew on 2nd September 1998.
