No engine I have ever flown has torched as much as the Goblin on start up. On my first night start on a Vampire ( 8 FTS Swinderby, last course, 60 years ago !) it was truly amazing ! We knew it torched but was not particularly noticeable in daylight, but at night it could be quite spectacular , , just as shown in the trailer ! Dont know about a glow in flight, we never did night formation in the Vampire !
A really great story !
