I also was lucky enough to fly both the Harrier and the 104 (CF).
LD ratio of 104 = no lift and not much more drag!!
We had one with no pylons and painted in black and white gloss paint would go super in mil power I know I did it one day as the Baron at fairly low level.
Longest trip low level Baden to Valley at 480/450 kts with enough fuel to divert to Heyford as the wind was out of limits at Valley.
Oh happy days.
