Best engine sound

Hi members.

Does anyone have a favorite engine sound from a commercial aircraft, modern or old.

Here are a few of mine.

The old 747 100 srs with Pratt and Whitney engines as they climb out above you.

The Vickers Viscount on take off and taxi

The Vickers Vanguard on approach

DC3 start up, take off.

BAC 1-11 during start up

Tristar during start up

A310 with GE engines on approach

Boeing 777 with GE90 engines on take off.

whats yours ?
