And yes, PSA would have been shut down within a year. We only had a handful of airplanes.
The only reason that Envoy voted yes is because AAG showed your MEC the exact plan for shutdown and how it was going to work. There was a timeline and everything in place to shut it down. They finally believed it and panicked and everyone voted yes.
Voting no was a luxury that Envoy had since you were so much larger than PSA. PSA had no bargaining power. Envoy voted yes as soon as they realized that they had no bargaining power.
