OK... I've worked through the backend database, and to be honest the event is descending rapidly into high farce.
Des Moines is as good a point as any to re-apply some order, so as of the departure from Des Moines (S026, valid from 2006-04-28), the following is the "written in stone" list of which aircraft belongs to which pilot:
Aircraft ID->Tail ID->Pilot ID->Pilot Name
796 PH-UKF EHM-0361 Karsten Frederiksen
797 PH-UDK EHM-0502 Desmond Klein
798 PH-UMC EHM-0654 Murray Crane
799 PH-URS EHM-1001 Robert Szikszo
800 PH-UPR EHM-1199 Philip Rolt
801 PH-UTY Spare
802 PH-UTB EHM-1417 Tamas Biro
803 PH-ULN EHM-1442 Luis Nunes
804 PH-UJH EHM-1500 Jim Hoyle
805 PH-UCB EHM-0001 Gergely Kosa
806 PH-UPN EHM-1703 Phil Nutt
807 PH-UCO EHM-1798 Conrad Oldcorn *
808 PH-UJG EHM-1821 Javier Goh
809 PH-UTT EHM-1633 Jose Rodriguez
810 PH-UEA EHM-1671 Ben Contreras *
811 PH-UEB Crashed
812 PH-UEC Spare
813 PH-UED EHM-1759 Ricardo Placido
814 PH-UEF EHM-1628 Jarle Bronstad
815 PH-UEG Spare
* These aircraft are currently at Chicago-Midway. Pilots that are "with their planes" still will need to "get their arses in gear" and shift them to Iowa post haste.
There is to be no arguments about this! Once we all leave Des Moines, this list is to be respected by all participants. As you can see, there are three spares in this "new" list. If you need to use an airframe that isn't explicitly listed as yours, use a spare and not someone else's.
That does not include crashes by the way; officially, if you crash you loose your place in the event! We've lost one airframe to a crash (Gergely's, as it happens, even though he wasn't flying it) and I'm not seeking to take this matter any further, but from Des Moines onward, everyone, be careful with your airframes - these alu birds don't grow on trees you know.
Personal note
By looking at the back-end database in conjunction with information provided on the PP website, it is clear who has "been naughty" and who is just a victim of circumstance.
I'm not going into any greater detail on this matter, this new list makes room for all current participants as long as we all abide by the rules of the event and we all fly safely. After all, that is what ProPilot flying is about.
Thank you.
