Ostend Airport , non stop action movie Boeing 707 / AWACS , glorious sounds 

JT3D engines on SU-AVZ but stage 3 noise compliant , new special cowlings , some noise reduction, from now defunct Burbank Aeronautical , flew onle a few years like this , when this 707 crashed during take off early 2004 at Cairo , no fatalities , destination Ostend , the final curtain

Those ARE bypass engines, just not the ridiculous high bypass engines like today. The JT3Ds sound heavenly too, unlike the boring engines of today.

707's could do things most modern airliners could not dream of. 757s are equally wonderful to hop on.
