Rumors that tower reported they were on fire on takeoff. Was an F-18D, you can tell from pictures of the ejection seats on them interwebs, older seats, not the new SJU-17. There are Deltas with the newer seat, but those are high lot jets most of which are in Marine fleet squadrons, but I digress. Yes seat/man seperation happens right after the chute opens (which is packed in the head box (heh). Winds of 20G25 in the Hornet are not that big of a deal, compressor stalls in the F404 are pretty rare unless you suck something down like a bird. They operate just fine at 70 knots and 45+ AOA. The Canadian jet that crashed was doing a slow speed/high AOA demo practice and lost a motor, usually about 25 AOA and 110 knots or so, 35 AOA is C/Lmax. On takeoff you'll rarely exceed single digit AOA.
Agree that one nozzle open, the other closed indicates an engine problem (speculation) however the three loud bangs everyone heard was probably the ejection sequence. Canopy, back seat, front seat. Know the guy in the back, good/smart dude. Hoping everyone on the ground is ok.
This is going to turn into a political shit storm given the vocal nature of local opponents to the base.
