Not necessarily The release of the hormone Relaxin increases during phases of cycle & in some women causes increassed laxity in joints; this can cause pain during exercise in SIJ due to lax ligaments; it's detrimental to joint stability during high velocity changing of direction.

Thanks for the heads-up. Weren't they already acting suspiciously? As self appointed "Sheriffs of Teddington“ was this a call from you to get a posse together & chase them out of town!? Or As Police officers, pulling them over & checking their docs: License, insurance, V5 & MOT!?

This condensing of the water vapour due to low pressure on upper surface can occur subsonic in the right atmospheric conditions. This plane is not necessarily at Mach1.

Yes Relaxin levels rise during 2nd phase of cycle & in some cause laxity of joints; can cause pain during exercise in joints such as sacroiliac joint & detrimental to joints during high velocity changes of direction. If you're affected regulate exercise intensity during this time

volunteer crew member meeting the Duke Of Cambridge today I'd no idea the number of "shouts" the crew are called to, helping destressed people! They do a fantastic job & they are local people in our community. Thank you & all the crew...

Words are spells. We learn to SPELL as children. A spell [words] can & are cast but only affect one if able to take hold. Ugly is a powerful spell cast be the weak. You are stronger than the caster. It is a conscious choice: You are a life saver, a firefighter & more Be beautiful

Clients are often surprised I have joint injuries, had some knee operations & got a bit of arthritis - when they ask why? I explain I did a bit of Judo when I was younger They often say they did as a kid too Judo, the gentle way edited video from Judo Motivation 2, youtube

If scientist is of mediocre importance, then publicly & moralistically they will be burnt & forgotten: But, if deemed v important science to a Nation or humanity, a way to use them regarless of views or deviations will happen. Operation Paperclip & Wernher von Braun comes to mind

PS Boeing is at fault in these tragic & needless losses. All in a chain play a part in preventing failure, but when the inbuilt problem has been poorly thought through, relying on 1 AOA sensor & MCAS is hidden by manufacturer, the chances of a successful outcome is small.

& been acted upon successively by maintenance engineers, operator tech dept, Boeing & aviation authorities (FAA CAA JAA) in chain that could/ should have prevented failure Many people “wittingly” or otherwise are in the chain leading to 737Max’s catastrophic failure - TWICE 🔚

... accepting 737Max into fleet will/ should have completed acceptance & compliance testing & airlines' Technical department should have studied the MM & IPC & questioned the new MCAS system. Pilots experiencing stabiliser issues as minimum will have entered event in Tech Log 🔛

Inconceivable Boeing “missed” potential issue & risk of MCAS in design process of 737Max: There will engineers/ designer(s) shouting, "I told you!" (but not publicly due to NDAs) Boeing incompetency set the 737max on pathway to eventual failure. But remember airlines 🔛

As former accident investigator, it’s amazing how accidents/incidents occur A chain, sometimes of seemingly insignificant events, each shaping pathway to incident or worse, catastrophic failure If it can go wrong, it will eg Concorde crash, much more than metal strip on runway 🔛
