Let's make a WAG that 20% of the pilots are going to vote "No" no matter what.

Another 20% will vote "Yes" to anything put in front of them.

This is pretty typical for just about any election on any matter, and I'll bet it was pretty close to reality in this case.

The battle was with the middle 60%. And 75% of those voted no.

The 1980 and 2008 Presidential elections, both decided with only 60% margins among the center of the electorate, were called "landslides." Both of those were near 60% voter participation.

One promise that the MEC kept, even if unintentionally, is the "historic" moniker. This TA was historic in how badly it failed.
