When you say "takeoff was aborted very last second", you mean as you were zooming down the runway, or before starting the takeoff sequence?

I hope the pilot knew about the fire before it was reported to him by another plane! They have warnings and alarms, right?

It looks like it was the same plane. It was probably something minor, or nothing at all.

It was the same plane (ship# 3514) with status showing "returned to gate" and then "Delayed due to aircraft maintenance (Arrived Gate 3 Hours Late)"

Yup, take off aborted at 75% Vto or so.

Don't think so, the pilot specifically mentioned that one of the planes in line for take off behind us, reported the flames coming out of the engine.

Heard that this is sometimes the result of some jet fuel in the exhaust that burns up.

Wow. I've experienced an aborted landing once or twice just as we were about to touch down, but never an aborted takeoff. Was the braking much more severe than what you experience on a normal landing?

Maybe a little, it was a little rough but perhaps just more unexpected than anything else.

Believe the correct terminology would be V1 for max calculated speed that can still abort the take off, if faster must take off. And RTO for Rejected Take Off. But hopefully a UA pilot can verify. I just never heard of Vto.

But I could be wrong. Has happened before and will most likely happen again.

Believe me, not trying to take away from a possible scary situation.

Flames out the front or back?

Back might just be a little fuel pooled somewhere, front is usually compressor stall/unstart.

V1 and Vto are the same thing...

Since the CFM56 is not normally equipped with afterburners, that may pose a legitimate cause for concern.

So, by "not normally" are you implying that afterburners are an option? Perhaps for those really, really short fields? This option would also make for interesting jumps out of places like SNA (Orange County / Santa Ana Calif.) that have noise restrictions.

There's also (any pilots please correct me if I'm wrong) Vr, which is the minimum velocity at which the pilot can initiate rotation (or pulling back on the stick to get the front gear off the ground). V1 is the maximum velocity at which the takeoff could be aborted and still have runway on which to stop.

Actually, there's a whole slew of V speeds: https://en.wikipedia.org/wiki/V_speeds
