I hasten to reinforce that it's not a picture I took - just one I found on t'internet. But I agree it is superb.
The other point of note is the upward tilt of the outer engines on the DC8.
AFAIK the 707's were all level. Anyone know why the '8 was like that?
I-42 I, too, have flown a chippy at sub 200 feet across Cheshire on many occasions, but in the LLR. It's much more interesting down there 'in the landscape' (even mid Cheshire isn't flat when seen from down there!) as you say waving your wings to folk who wave at you, and with the power and speed up (a whole 105 kts, maybe!) trimmed slightly nose up with the stick held forward in case 'instant height' was required to comply with the 500' rule or powerlines (naturally, one flew around towns and villages!). The Chippy's lovely harmonisation was even crisper with those extra few knots!
Probably not advisable today when everyone has a video camera on their phone and even legal low flying broadcast on YouTube can invite 'questions'.
