Christmas Spectator Crossword By Lavatch( Another Learning Experience For Me...)

[Matakari]

Good evening, I’m about to end another learning experience from this one!I’ve got all of the Unclueds except 24a (?O???L ) and 28a(??ALOR). Help to unravel the following which are still confusing me:
37a Heavyweight punching pilot directly (2,4) : AT?N?? ( AT ONCE)
23 d Spot, we hear, and encourage echinoderm (3,3): S?A??G ( SEA PIG)
And the answers for these thanks:
8 d German article about X-ray for membrane (5) : E?I?E
10 d It’s put on e.g. Oxford building with nothing in (5) : ?HO??
34 d Five soldiers past gulf (6) : VORA?O ( VORAGO )

[ProfessorMaisie]

24 follows 28, 4 words (the same word is in both ??al)

[ProfessorMaisie]

10d has been given before - SHOED (an oxford is a shoe).

[Neveracrossword]

Matakari, I gave you Shoed before, and mentioned then that it had already been answered. I expect several of your others have already been answered and parsed.

I'm glad you're seeing this as another learning experience.... though there's still time to enter, I think!

[Matakari]

Many thanks for the generous learning experience, all!
On to Doc's New Year's Offering which appears quite doable
and within my range!

Here's hoping

[Neveracrossword]

Matakari, I feel you should have a Ph.D by now - AB has helped you with the 'learning experience' of well over 600 Spectator puzzles!

This week's Doc is definitely doable, and I think you managed a couple of his in 2022.
