“	Henry's been captured by the government and can wipe away his debt by doing them a favor. The Toppat Clan, a group of international thieves, has been a thorn in their side for sometime. They're sending you in to bring them down.	„

Infiltrating the Airship is the fourth game in the Henry Stickmin series. It is the sequel to Stealing the Diamond and takes place before Fleeing the Complex and is named as Episode 3 of the Henry Stickmin story. The game has four different endings and one fake ending.

The game introduces the Government and the Toppat Clan - two opposing factions that would play major roles in Fleeing the Complex and Completing the Mission. Alongside the factions, Charles Calvin, Captain Hubert Galeforce, Reginald Copperbottom, and the Right Hand Man make their first appearances in Airship; all would go on to become staple characters in the series.

Plot

After stealing the Tunisian Diamond from the museum, Henry has been kidnapped by the Government, waking up on board a helicopter. There to greet him is Captain Hubert Galeforce, who recognizes Henry's skills as a criminal, and gets him to put them to the test in a mission.

The Government has trouble capturing a collective of criminals known as the Toppat Clan. They are unable to pin them to criminal charges, thus they can't take legal action against them. Henry's mission is to infiltrate the Toppat Airship in an effort to bring them to justice.

Noting Henry's lengthy criminal record (attempted robbery, escaping prison, and grand theft), Galeforce informs him that all charges against him will be dropped, if he gets the mission completed. Charles Calvin, the helicopter pilot, takes Henry closer to the Airship and asks him where to disembark.

Transcript

[Game opens up with Henry Stickmin sleeping, then wakes up on board in a helicopter leaning against a box]
Captain Hubert Galeforce: Well, well... Look who finally decided to wake up. You've been quite elusive, but your skills make you worth the catch. You'll be perfect for the job. We've been having some issues with a group of thieves known as the Toppat Clan. We know they're guilty, we just can't pin them to any crimes. You will be going into their airship to bring them down. I don't need to remind you that we've got you on several charges: attempted robbery, breaking yourself out of prison, and even stealing the Tunisian Diamond. We've got quite a lot of counts on you. Do this job right, and we'll drop all charges against you. Charlie here will be bringing you close to the airship. The rest is up to you. Find a way to bring them down, and you'll be a free man.
Charles Calvin: Hey, uh, how do you want me to bring you in?

Trivia

All other Characters except Henry, Hubert & Charles Don't Have Eyebrows.
The contents in the book of Henry's crimes depicts scenes from previous Henry Stickmin games. In the legacy version, the scenes shown are chosen at random. In the remastered version it shows the ending the player most recently viewed:
- One of the six scenes from Breaking the Bank
- Picture of drilled cell floor if the players choose Badass Bust out Ending
- Felix White's card if the players choose Lawyered Up Ending
- Broken cell door if the players choose Sneaky Escapist Ending
- Penny if the players choose Unseen Burglar Ending
- Piece of dinosaur egg and CCC card if the players choose Just Plain Epic Ending
- Johnny Panzer's morgue ID tag if the players choose Intruder on a Scooter Ending
  - For some reason, Puffballs decided to use legacy version images from Escaping the Prison and Stealing the Diamond (Excluding in Intruder on a Scooter ending aftermath which has given remastered image). However, Breaking the Bank is the only one which get remastered instead. The only change is that the writings has been fixed to be readable.
This is the first game in the series where the endings have completely different fates for Henry, the previous games all involved the same tasks being done.
This is the only Henry Stickmin Legacy game to still be on a mobile application store, due to the others getting removed for various reasons (including copyright).
Not counting Breaking the Bank, this game has the least quick-time events, with 3.

Glitches

During the Rapidly Promoted Executive/Relentless Bounty Hunter route, if the player chooses Spike Ball or Eject just a second before the timer runs out, it will show two fail messages at the same time.
- The same happens when the players go to the Quarters Hallway from the map after getting all the other conditions for the Biggol Sword; Henry will receive the sword but encounter a fail screen.
- This is also happening during Government Supported Private Investigator route, during archives room QTE.
In flash version, there's an error in the achievements, in which the ending GSPI is named GAPI. This was corrected in the mobile version.
