You can fine 100-400 pics here: https://photography-on-the.net/forum/showthread.php?t=373778
Not sure where to find pics of 70-200 with a TC.
70-200 f2.8 IS with 2X converter at 220mm...
I have the 100-400 and just love it for airshows. IMHO the 70-200 wouldnt cut it for airshow duty.
I've never tried the 70-200 for an airshow. My 100-400 does just fine.
The biggest problem I have with the 100-400 these days is prying it out of my wife's hands...
