NoReverseMatch Error Django - UpdateView

I have a view which the user can create/update their posts. However, when the user has finished their editing, I want them to return back to the post (summary). However, there's an error somewhere which I can't find. Any ideas on what the issue may be?

Error: 1) Reverse for 'aircraftdetail' with arguments '()' and keyword arguments '{'id': 2}' not found. 0 pattern(s) tried: []

2) return HttpResponseRedirect(instance.get_absolute_url())

3) return reverse('aircraftdetail', kwargs={"id": self.id})

views.py

def AircraftUpdate(request, id=None):
    instance = get_object_or_404(Aircraft, id=id)
    form = AircraftForm(request.POST or None, instance=instance)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return HttpResponseRedirect(instance.get_absolute_url())
    context={"aircraft":instance, "form":form}
    return render(request,'aircraft_form.html',context)

Models.py

class Aircraft(models.Model):
    title = models.CharField(max_length=50, default="")
    image = models.ImageField(upload_to = 'static/image_upload', blank=True)
    cost = models.DecimalField(max_digits=8, decimal_places=3)

def get_absolute_url(self):
        return reverse('aircraftdetail', kwargs={"id": self.id})

Urls.py - Aircraft

urlpatterns = [
  url(r'^detail/(?P<id>\d+)/$', views.AircraftDetail, name='AircraftDetail'),
  url(r'^detail/(?P<id>\d+)/edit/$', views.AircraftUpdate, name='AircraftEdit'),
  url(r'^$', views.AircrafList, name='aircraft'),]

Urls.py AviationSite (Main)

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'aircraft/', include('aircraft.urls')),
    url(r'^login/', login_view, name="login"),
    url(r'^logout/', logout_view, name="logout"),
    url(r'^register/', register_view, name="register"),
    url(r'^aircraft/create/$', AircraftCreate),]

Your URL pattern has `name='AircraftDetail' (capitalised 'A' and 'D'):

url(r'^detail/(?P<id>\d+)/$', views.AircraftDetail, name='AircraftDetail'),

That does not match the aircraftdetail (all lowercase) where you call reverse:

return reverse('aircraftdetail', kwargs={"id": self.id})

Change one of them to make them match (all lowercase is more common in Django).
