Easyjet UK Flights - 05 Mar 2010 - Trail and No Trail
UPDATED:14th July 2010
This is part of some research I have yet to fully write up.Like many people, I have become concerned about the number of these trails on some days and therefore have even gone to the trouble of investing in an AirNav RadarBox "virtual radar" device for my computer, so that I can determine a little more about air traffic movements over my house. (The CAA and other people I wrote to could not provide this information in retrospect).
These can be purchased in various places, including e-bay: The cost includes a 12-month subscription to the database service which allows a number of the various flight details to be downloaded.
Having detected, identified and photographed these 2 EasyJet flights, I made this video and wrote the letter below recently (will post any replies on my website http://www.checktheevidence.com/ later) I just sent this letter, along with this video and the other data referenced here to Easyjet (UK). I will be writing more about this over the coming weeks and months - but it is time-consuming working through the data I have collected. Here is a copy of the letter (including still images)
Like quite a few people I was surprised to detect this result – as I had kind of assumed that only unmarked planes would be “caught” making trails.
I was asked by someone about the AirNav RadarBox picking up military flights. Here are the notes from the manual for the unit:
Why can I see aircraft in the list but they do not appear on the map?
Some aircraft, although they are fitted with ADS-B equipment, do not transmit their position. Without position information, it is impossible to display the aircraft on the map. In the example below, the first 2 aircraft in the list have ADS-B equipment, but they are not transmitting position information. However, it is still possible to see the identity and type of the aircraft and their altitude. The last 2 aircraft are transmitting full position information (shown by the Globe in the first column) and will appear on the map. Note that military aircraft will often show in the aircraft list, but for security reasons, do not transmit their position.
Using the Radarbox over time allows data to be captured and I am hoping to make some comparative measurements between days with no trails and days with high numbers of trails to see what emerges. Some of the log files I have collected have 800,000 lines of data.
flights do not broadcast their position either - only their height - and some don't broadcast

Re: Easyjet Air Traffic Enquiry
I am writing to enquire about a “persistent jet trail” incident which occurred over (or nearly over) my house on March 05, 2010.
I have become concerned about the number of these trails on some days and therefore have even gone to the trouble of investing a not inconsiderable amount in a “virtual radar” device for my computer, so that I can determine a little more about air traffic movements over my house.
My question is fairly simple. I tracked 2 Easyjet flights over my house – details below – and one flight was leaving a long, persistent trail, the other was not. I photographed them and took a short video clip. I have made this into a video, a copy of which is on the enclosed disk. You can see in the 2ndvideo clip that there is another plane, ahead of EZY239 which is also leaving a much longer trail.
So, why was one leaving a long trail and the other was not – they were flying at almost the same height, at nearly the same speed, in the same general direction, on the same day and it was the same type of aircraft.
I would be very pleased to have an explanation about this – and I know quite a few other people who are also interested in this subject.
