#ItsTheHeightSTUPID!
OVERFLYING (HIGHER) PLANES LEAVE BIGGER LONGER-LASTING CONTRAILS THAN LOWER LEVEL FLIGHTS.
Overflying planes leave bigger, longer-lasting contrails primarily because they fly in significantly colder and more humid atmospheric layers, typically at altitudes above 35,000 feet. The ambient temperature and moisture at these specific elevations allow engine exhaust to instantly freeze into persistent, heat-trapping ice crystals. [1, 2, 3, 4, 5]
The formation and size of a contrail depend on several factors:
Altitude and Temperature: Contrails usually appear at or above 20,000 feet. However, "oversized" or persistent contrails that linger and spread into cirrus clouds often form much higher up, where temperatures drop below -50°C. [1, 2, 3]
Atmospheric Moisture: A plane can be flying at high altitude, but if the surrounding air is dry, the contrail will quickly sublimate (disappear). Larger, spreading contrails only persist when the plane cruises through "ice-supersaturated regions" (ISSRs). [1, 2, 3]
Aircraft Type: Research shows that highly fuel-efficient modern jets and private jets tend to cruise a kilometer higher (often above 40,000 feet) than older, heavier commercial airliners. These extreme altitudes make them more likely to generate persistent, contrails.
Scientists have discovered that altering the altitude of a flight by as little as 2,000 feet—either slightly up or down—can frequently maneuver a plane out of the cold, humid air masses that cause contrail formation.

#LOOKtheOVERflightSURGE
Overflights (planes flying through UK airspace without landing) have surged, increasing by double-digit percentages in key sectors over recent years, and exceeding pre-pandemic 2019 highs. Overall commercial flights across Britain have grown significantly over the last decade, reaching roughly 2.7 million flights annually. [1, 2, 3, 4, 5]
Decade Traffic Trends
Total Flights: In 2015, total flights handled in UK airspace hovered around 2.4 million. By 2025, annual flights reached 2,536,156, pushing towards the all-time record set in 2019. [1]
Overflight Surge: "Non-Transatlantic Overflights" (planes entering UK airspace without stopping at UK airports) have been the fastest-growing sector, jumping by 17% in recent year-on-year comparisons. [1]
Transatlantic Growth: Flights crossing the Atlantic via UK airspace have also experienced substantial spikes, with periods showing over 10% growth, particularly on routes connecting mainland Europe to the United States. [1]
Top Growth Routes
The most rapid growth within European overflights involves cross-border routes using British skies. Some of the most significant routing surges include: [1]
Ireland to Poland
Ireland to Italy
Norway and Spain [1, 2]
Infrastructure Impact & Modernisation
Because this massive growth has led to heavy congestion, the UK is undergoing the biggest airspace upgrade since the 1950s. The Airspace Modernisation programme led by the Airspace Change Organising Group aims to phase out 70-year-old routes, allowing aircraft to fly more direct paths, thereby reducing delays, cutting emissions, and avoiding the need for conventional "stacking". [1, 2, 3, 4, 5]

Our ATC (Air Traffic Controller) gives a quick run down of some recent CONTRAILS, (Not "ChemTrails"!)
(FL= Flight Level, 330=33000ft etc)
[06/07, 15:39]: Over flights between fl 330 and 380 different engine types, heading to Germany. One crossing north/south from Spain to Manchester smaller engine at FL 330. Another adding in now Malta to Dublin.

Another dynamic up-to-the-minute speech by #PiersCorbyn at BBC TruthHour 9July 2026.
He reminded people that this hot (Br+Ir) weather confirmed his WeatherAction Long-Range forecasts & revealed that now MetOffice forecast estimates for the next few weeks had moved to be more in line with his.
He asked BBC to watch closely the expected release of Epstein files on the day, July9 - & consequent incrimination of Trump & Starmer and said Trump was doing crazy manoeuvres to hide this.
He said Nigel Farage is also playing games to hide scandals but this gives us a great opportunity to raise key issues and (to applause) that he will stand in the Clacton By-Election. He spelt out key policies and exposed some of Farage's errors such as suggesting Tony Blair should be a "Vax-Czar"!

He also said as an MP he would expose and stop Govt funding of Charlatan groups such as the "SunDimming" project housed in the British Library building.

You know the right bin is Piers Corbyn.
For proper representation and accountability,
Vote him to win for Clacton-on-Sea.”
