A question for Jetstar drivers into Avalon

[Buster Hyman]

Thanks metro. I'm doing a risk assessment for my CFA Brigade & wasn't sure what height you passed over us at. The noise bit was out of curiosity.

Thanks Baz. It's definitely an engine type noise I hear, sort of like when machinery powers down however, as my qualifications fall a little short on the "engine-y type noise" identification, I'll accept any hypothesis!
