Well done IO540!
We have flown together a few times in his beautiful aircraft and he in some of the aircraft I fly. Good company and ever interesting posts!
As to why we do it well I am afraid I have been posting here as long as many - although I think a few have been around for even more years.
It is a great way of keeping up with developments, sharing a little gossip and banter and, hopefully, passing on a few experiences.
