I remember the P51 well. If my memory is right, there was a US-reg. B25 Mitchell around for quite a few months in 1966-67 as well, painted red and green. I've also got vague memories of a Douglas A-26 Invader around this time as well, used as an exec. transport believe it or not. Lucky suits, they must have been deafened by those massive P & W R2800's roaring away inches from the fuselage.
On a different topic,is LTN still the busiest airport in Europe for foreign-reg. business jets. Just wondered because on my last visit there could have been around 50 on the ground, not counting those inside the hangars.
Cheers, and thanks for the LTN memories Mr Bear.
