This is usually just to check that there isn't many of the same aircraft already in the database, to avoid the "baddouble" rejection.
I often have to chuckle at previous uploads from years gone by, and are truly AMAZED at how far we've come in the last 3-4 years. Just thought I'd show one of my recent uploads (Self-plug !! ) ...compared to the Prince of Airliners.net ('cause he's 2nd at the moment.... ), that being AirNikon !
No responses needed ..... just something to look at ...and a SELF-PLUG ! ..........Shaun
