That tweet was made the day of the crash and is rubbish. There has been no credible claim by any group and IS in particular have very defined media release methods.
Likewise the "fireball video" is not footage of the crash and is more likely space debris burning up.
Additionally I personally take everything said by the Egyptian authorities with a pinch of salt. They're quick to point to terrorism this time because it means the finger of "blame"/"failure" points away from Egypt.
I agree , those bad terrorists, like all the rest of the world just cant be stopped! But an a unsafe plane -someones responsibility.
But since seeing ACARS, I def have some notions about "mechanical". IMO she was worked hard. But I thought , "you need to see if your conclusion has any merit"
So I went off sleuthing! Here is what I found out
My point of reference was only the 5 days on 24 Radar site.Typically tho planes go the same segments day after unless some interterupts the "plan".
We know she was up 17 hours with the 24 hours prior, and from radar site, this was relativy consistant'
Latest I could find was from 2014, and there are variables. Age, an airlines routes etc etc , but just to get an idea.
here is what i found :
Average Daily Airborne Hours of Total Operating Fleet
American 9.8 per day
Delta 10.5
NW not on chart ?
SW 11
jetblue 11.7
United not on chart?
11.3http://web.mit.edu/airlinedata/www/2014%2012%20Month%20Documents/Aircraft%20and%20Related/Total%20Fleet/Average%20Daily%20Block%20Hour%20Utilization%20of%20Total%20Operating%20Fleet.htm
Metal fatiage is more like tire wear than having anything to do with like engines. Frequency pressurize /depressurze.
Also we could have a intercontentiial flight with 17 hours in the air,and this aircraft with 17 hours in the air.Takeoff, climb,descent,landing are stressers.
If we were using identical aircraft types - the one with the short hops vs long run- the machine on the hops is def being stressed out much much more moo
more here it would not copy and paste!
