How HS2 gets past Birmingham - Airport Interchange & Delta Junction

Looking by drone at how HS2 gets past Birmingham and current construction status, including the Interchange Station linking to Birmingham Airport, various road changes on & around the A45 & A446, numerous crossings by HS2 of the M6, M42 and M6 Toll motorways, a whole load of power lines, and the delta junction where the Birmingham spur of HS2 links to the main line. Also the new link road being built to the new M42 J5A and some gratuitous shots of the airport runway because I unexpectedly got permission to fly a drone there after lengthly discussions with various airport officials (DO NOT try that without getting permission and air traffic control being aware and OKing it). Don't ask me how to get that permission, I don't know that they'd give it again and if you knew the regulations well enough, you'd know who to ask.

All drone footage original and mine.
