When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

they were probably already going too fast down the runway when they saw a birdstrike might occur

This is at accident report stage so I think the mix of tenses might be confusing
In fact, the takeoff was aborted just after becoming airborne in order to avoid a flock of birds as they didn't have enough ascent to avoid them, so they tried to land again but hit the runway heavily.
However, IF they had struck the birds, engine failure would have occurred and, from that position, an aborted takeoof would not have been accomplished safely

Reference comments
Rejected takeoff
In aviation terminology, a rejected takeoff (RTO) or aborted takeoff is the situation in which it is decided to abort the takeoff of an airplane. There can be many reasons for deciding to perform a rejected takeoff, but they are usually due to suspected or actual technical failures, like an engine failure such as a compressor stall occurring during the takeoff run.
A rejected takeoff is normally performed only if the aircraft's speed is below the takeoff decision speed known as V1, which for larger multi-engine airplanes is calculated before each flight. Below the decision speed the airplane should be able to stop safely before the end of the runway. Above the decision speed, the airplane may overshoot the runway if the takeoff is aborted and therefore a rejected takeoff is normally not performed above this speed, unless there is reason to doubt the airplane's ability to fly. If a serious failure occurs or is suspected above V1 but the airplane's ability to fly is not in doubt, the takeoff is continued despite the (suspected) failure and the airplane will attempt to land again as soon as possible.

Take off - distinct stages
Stages of take-off
1. Ground run. Aircraft accelerates horizontally up to rotation speed,
VR. Altitude of aircraft constant ⇒ CL, CD constant.
2. Rotation. Aircraft nose is pitched up so at end of this phase lift
exceeds the weight and hence the aircraft accelerates vertically.
3. Flare. Flight path angle is changed so that it matches climb angle
(NB: flight path angle and pitch angle are not the same. Flight path
angle is angle cg moves relative to ground)
[*** AND ALSO part of the take-off ***]
4. Initial Climb. Aircraft climbs at steady angle to screen height
(hs ∼ 15m) CL, CD constant.

It makes more sense to me if the pilot was in a later stage of the takeoff.

Please excuse my inconsistent usage of tenses :)
This is just following my interpretation, and I have no plane piloting experience.
While ascending, the instructor saw the birds and was faced with a dilemma: abandon takeoff and crash land or continue with takeoff and hit the birds. If he had chosen the potential bird strike, it would likely have led to engine failure and dire consequences, since it would have been unsafe to eject himself and his student from the plane at that altitude. Therefore, he abandoned takeoff, the safer but still risky option.
I admit I hadn't checked the link with all the context when making my first comments but the meaning of the phrase remains as is.
I already added a note simplifying the actual sequence of events and the WHAT IF they HAD hit the birds and had NOT been able to abort the (complete) takeoff safely. It could be argued that once airborne (as is the case here) they HAD actually taken off, https://www.collinsdictionary.com/dictionary/english/takeoff
so they re-landed rather than had an aborted takeoff.
But anyway, the phrase as it stands in the sentence means they could not abort (or COMPLETE might be preferable) the takeoff safely from that particular Third Conditional position of hitting the birds and having engine failure (IF that HAD happened/BUT it did NOT!).

The pilot noticed a flock of birds during take off from Cranwell, Lincs. He elected to land rather than fly through them. The heavy landing burst both main tyres and collapsed the nose wheel leg. Allocated to 8826M at Church Fenton
