Depends on your judgement - if you are going to hit the incursion or miss it.
Therein lies the real problem.
While the military transport flyer has a lot more performance information than does his civil colleague (cue for Galaxy Flyer to wax lyrical on the subject), the latter is very hard pressed to make any sort of realistic judgement other than at the low/high speed end of the takeoff.
For instance, the accident at SYD involving TJA and referred to previously by CC is well worth the read just for this aspect (learn something new every day .. wasn't aware that Doug was the F/O on that occasion ... and was it really that long ago ?).. hence the civil emphasis on procedural decision making during the takeoff .. might not always give the best result but should have a much higher probability of success than encouraging the crew to "wing it". It is interesting to note that the crew apparently first became aware of the conflict at around 100 kts, probably could have stopped with around 2200 ft to spare .. but were convinced that there wasn't enough room to do other than drag the 727 over the DC8. The fact that they very nearly got away with the strategy doesn't negate the observation that stopping was the more appropriate action on this occasion. The DCA crash comic article on the accident very clearly emphasised this difficult decision situation for the crew on this occasion.
I rest my case ...
